ジャーナル 認証ありThe linear polarization of coherent bremsstrahlung was measured by comparing one dimensionally projected angular distribution of symmetricpair electrons with the theory. The distribution was measured with a wire chamber on both the electron and positron sides independently of each other. polarizations obtained on both sides agreed well.
The polarization was measured at 153 MeV for various orientations of the crystal. The polarization spectrum was in good agreement with the theory. A large polarization at the null injection angle of the incident electron beam to the crystal axis [110] is discussed in relation to a partial failure of the Born approximation and to the crystal dislocation.
The systematic error for the polarization, temperature rise of the crystal, problems in the measuring method, etc. are discussed.抄録全体を表示PDF形式でダウンロード (1388K) -

ジャーナル 認証ありSpectra of deuterons from (p, d) reactions on 18 nuclei with neutron numbers N between 52 and 82 were measured at an angle of 20° with 52-MeV incident protons. In each spectrum a broad bump with the distinct top is observed at excitation energies of several MeV or higher. From the systematic behavior of the bump it is inferred that the top of the bump stands for an approximate position of the 1 g9⁄2 neutron state, and energies of this state are estimated from the observed spectra. The estimated energies are compared with calculated ones and a reasonable agreement is obtained. The systematics of the energy difference between the top of the bump and the ground state in the residual nucleus is discussed on the basis of the simple pairing theory, and the results which are well consistent with the above inference about the top of the bump are obtained.抄録全体を表示PDF形式でダウンロード (928K) -

ジャーナル 認証ありThe averaged magnon Green function in a random Heisenberg ferromagnet which has two kinds of exchange integrals JA and JB randomly distributed is calculated by the coherent potential approximation. The density of states of magnon is calculated for various cases, and the correct localized mode is obtained in the low concentration limit. The critical concentration is obtained for two cases, JA>0, JB<0 and JA>0, JB=0. The magnetic properties for the two cases at the critical concentration are different from each other.抄録全体を表示PDF形式でダウンロード (848K) -

ジャーナル 認証ありThe Ising of spin 1/2 with the nearest-neighbor interaction, in which nonmagnetic impurity atoms are dissolved, is investigated. Based on the identity ⟨si⟩=⟨tanh(KΣsj)⟩, decoupling approximation is introduced for treating the many-spin correlation functions. The dependences of the critical temperature and of the spontaneous magnetization on the impurity concentration are calculated for two- and three-dimensional lattices. The results for the critical temperature and the critical concentration are better than the results of the results of the extended molecular-field approximations of Mamada and Takano, or of Oguchi and Obokata. Especially for the three-dimensional lattices the critical obtained agrees with that of Sykes and Essam, estimated from the series expansion.抄録全体を表示PDF形式でダウンロード (716K) -

ジャーナル 認証ありThe band structure of crystalline CdSb has been calculated by the use of empirical-pseudopotential method in the single space group representation. Calculated band structures shown that both the bottom of the conduction band and the top of the valence band are on the symmetry line [100]. It is found that the lowest energy gap of 0.49 eV is indirect one from ∑4 to ∑1 on this line. Direct transition gaps are assigned by using the selection rules. The anisotropy of the effective mass at the top of the valence band is such that (mh*)a:(mh*)b:(mh*)c=1.60:3.35:1.00 and is in good agreement with the determined from the experimental from the experimental results of the Hall mobilities.抄録全体を表示PDF形式でダウンロード (988K) -

ジャーナル 認証ありDirect observation of the spin densities on the F−–Cu2+–F− antibonding orbital in ferromagnetic K2CuF4 was made by neutron paramagnetic diffuse scattering. The covalency effect appeared as an anomalous modification of the form factor of the Cu2+ ions as suggested early by Hubbard and Marshall. The form factor at small angles was worked out precisely by the use of the intense critical scattering in the form of ridge reflecting the two-dimensional nature of this compound. As expected, a well behaved small peak appeared at lower scattering angles less than sinθ⁄λ∼0.1. The height of this peak as well as the flatness of the form factor at higher scattering angles were consistent to the NMR data and the theory.抄録全体を表示PDF形式でダウンロード (960K) -

ジャーナル 認証ありThe magnetic critical scattering from a single crystal of γ-Fe0.537Mn0.463 has been studied around the (001) and (110) reciprocal lattice points. It has been found that the longitudinal spin correlation becomes divergent at the Néel temperature TN of 479.0±1.5 K, the parallel staggered susceptibility χ⁄⁄(Q) obeys a power law of α(T−TN)−1.35±0.05, in contrast with the temperature independent static susceptibility. The transverse spin correlation, however, remains finite at TN with the inverse correlation length of about 0.038 Å−1. The anisotropy of the spin correlation has been suggested not due to the crystal anisotropy, but to either the anisotropic exchange interaction or the anisotropy of the non-interacting spin susceptibility of d bands. The anisotropy of the scattering profile with respect to the wave vector around the reciprocal lattice points has been found much smaller than that expected for the type I antiferromagnet with the short range interactions.抄録全体を表示PDF形式でダウンロード (1452K) -

ジャーナル 認証ありThe problems on the magnetic dilution in the ferromagnetic system are discussed by the use of the Ising model of spin 1/2. In addition to the exchange interaction between nearest neighbors, the next nearest neighbor (n.n.n.) interaction has been taken into consideration, and the magnetic properties are calculated by the method of concentration expansion. Particularly the critical concentration and the concentration dependence of the Curie temperature have been calculated for several lattice structures. In some crystal lattices, the n.n.n. interaction concerns to the change of the dimensionality of the magnetic lattice and then the effects of the n.n.n. interaction are quite remarkable in the concentration dependence. The numerical values of the critical concentration and the Curie temperature calculated in the present method are compared with the results previously calculated by various methods and good agreement is obtained.抄録全体を表示PDF形式でダウンロード (968K) -

ジャーナル 認証ありSpin wave resonance for a series of fcc Fe–Ni alloys has been measured in order to study the exchange stiffness constant D. In general the resonance field vs the square of the spin wave mode number (n) curve is linear for high values of n, whereas some amount of deviation from linearity occurs for low values of n. This is considered to be due to the inhomogeneous demagnetizing field of the sample. We can determine the value of D from the linear part of the curve, provided we have a sufficient number of observed modes. As a supplementary means, we have also made low temperature magnetization measurements from which the value of D was derived. Consistency between these two kinds of measurements is ascertained. The composition dependence of D is not quite coincident with that derived from the neutron small angle scattering experiments by Hatherly et al. The data are discussed both from the standpoint of localized electron model and collective electron model.抄録全体を表示PDF形式でダウンロード (936K) -

ジャーナル 認証ありThe ESR spectra of Cu2+ doped in TGS were analyzed without any assumption in the symmetry of the crystal field. At room temperature, the directions of the maximum principal values of the A- and g-tensors agreed within 4° with the normal to the plane containing the two glycines, glycine 2 and glycine 3. The directions of gx and gy were nearly parallel to the bisector lines between N–N and O–O. At 77 K, two kinds of the absorption lines, the spectrum I and spectrum II, were observed. The former was decreased while the latter increased in intensity with increasing temperature. The parameters p, a12 and κ in the ligand field were determined using the principal values of the g- and A-tensors. The p-values for the spectrum I and spectrum II were 0.036 cm−1 and 0.0776 cm−1, respectively. This change of the p-value indicates that the electron cloud in Cu2+ ion contracts with the increase of rotation frequency of the protons in NH3.抄録全体を表示PDF形式でダウンロード (620K) -

ジャーナル 認証ありElectrical conductivity (σ) of pyrolytic graphite along the basal plane was measured at room temperature in the presence of hydrostatic pressures (p) up to 20 kb. the pressure dependence coefficient d ln σ⁄dp evaluated was only order of 10−3/kb, despite compressive stresses gave rise to a suppression of lattice vibrations, and also to an increase of the carrier concentration (N) with a rate of d ln N⁄dp\gtrsim10−2/kb. Such a discrepancy has successfully been removed by taking into account the pressure-induced change of the effective mass of carriers, which functions so as to cancel the increment of σ due to the increase of N. Calculations were performed on the basis of an effective mass approximation for the Slonczewski-Weiss band model. Thus, the participation of carrier-carrier scattering proposed by Yeoman and Young is excluded from responsible mechanisms. Discussions given of the c-axis conductivity on the same basis have also yielded a success in accounting for the pressure dependence.抄録全体を表示PDF形式でダウンロード (624K) -

ジャーナル 認証ありThe present paper gives the results of direct observations on the formation process of the 9R martensite in AgCd. A direct process of the β′ to 9R transition is not realized but the transition is the β″ to 9R type. The β″ phase, formed from the β′ one before the martensitic transition, is not any precipitate in the β′ one. The martensite is produced as result of an enhanced fluctuation of the β″ phase: The fluctuation seems to be due to softening of a particular phonon mode. Based on the consideration on the phonon mode to be softened, nature of the martensitic transition in AgCd is discussed. The exact structure of the martensite is also determined. In addition, a common mode of the martensitic transition in the other β-brass type alloys is briefly suggested.抄録全体を表示PDF形式でダウンロード (1180K) -

ジャーナル 認証ありThe result of a rotating-specimen measurement of the angular correlation of annihilation radiation in Cu in the collinear geometry has been compared with the topology of the Fermi surface with evaluating the umklapp effect on the electron wave function in pseudo-plane-wave scheme. The agreement is fairly good within a few per cent of the mean counting rate. A significant increase in the height of the ⟨111⟩-peak is, however, observed in the experimental curve, which suggests a higher mean annihilation rate of the neck electrons than that of the other ones.抄録全体を表示PDF形式でダウンロード (496K) -

ジャーナル 認証ありThe first-order approximation to the partial annihilation rate in a hypothetical monovalent metal having a nonspherical Fermi surface has been evaluated numerically by utilizing a many-body theory associated with the two nearly-free-electron bands. The nonsphericity was introduced by a pair of zone faces to which the Fermi surface is attracted to from pair of short necks. The rotational symmetry around the reciprocal-lattice vectors relevant to those zone faces was also assumed.
The result gives higher enhancement of the partial annihilation rates of the neck electrons than that of the other ones. A careful examination of the present computation shows that the higher enhancement is attributable to the smaller gradients of the change in energy near the necks. Similar effects may be found also in more general cases.抄録全体を表示PDF形式でダウンロード (488K) -

ジャーナル 認証ありThe magnetic field effect on the hypersonic attenuation in Sb-doped Ge has been measured over the range from 0 to 200 kG at liquid He temperatures. The attenuation was observed to decrease as the magnetic field was increased at high field. The magnetic field dependence of the attenuation in the case of 1×1015/cm3 doped specimen differs from that of 1×1016/cm3 doped specimen. The experimental results are not quantitatively explained by the theoretical treatment which takes into consideration only the Zeeman effect on the single and the triplet states. If it is assumed that the effective Bohr radius of the donor electron is larger than the known values by other experimental methods, the semiquantitative agreement is obtained by calculating the shrinkage effect of the donor wave function.抄録全体を表示PDF形式でダウンロード (928K) -

ジャーナル 認証ありThe principal components of an electric field gradient tensor at a site of 23Na nucleus in NaNO2 irradiated with γ-ray have been studied under the precise temperature control. temperatures at which the asymmetric parameter η of the EFG tensor indicates anomalies decrease with the γ-ray irradiation. Especially, the temperature at which η becomes zero decreases monotonically with increase of the irradiation dose and this result does not seem to contradict an interpretation that the ferroelectric phase changes to the ferroelectric-sinusoidal phase at the temperature. The relation between the EFG tensor and long range order parameter is also confirmed.抄録全体を表示PDF形式でダウンロード (644K) -

ジャーナル 認証ありThe absorption, emission and its excitation spectra of Ag− centers in NaCl, NaBr and RbCl crystals were investigated at various temperatures. Most of the properties of these centers were found to be qualitatively similar to those of potassium halides, except that NaBr does not show C emission. The third moment of the C band shape function was obtained as a function of temperature for KCl and RbCl, and was compared favorably with the Nasu-kojima theory. It is concluded that the linear electron-lattice coupling approximation is quite satisfactory for Ag− centers in various substances so far studied.抄録全体を表示PDF形式でダウンロード (956K) -

ジャーナル 認証ありMagnetoabsorption of indirect exciton has been studied in AgCl and AgBr at 4.2 K. A new absorption appears on the lower energy side of the zerofield absorption edge when a magnetic field is applied. Kinks are observed in this absorption curve in a high magnetic field. Their dependences on the magnetic field are analysed by taking an electron-hole exchange interaction into consideration. It is concluded that the new absorption is due to a triplet exciton, and the highest tops of the valence bands in both AgCl and AgBr are at the L-point in the Brillouin zone, their states being (L4−, L5−). Exchange energy Δ and effective g-values are estimated as Δ=0.79 meV, gc=1.9, g⁄⁄v=0.7 and Δ=0.33 meV, gc=2.5, g⁄⁄v=0.5 for AgCl and AgBr, respectively.抄録全体を表示PDF形式でダウンロード (768K) -

ジャーナル 認証ありThe switching transients in Rochelle salt were investigated by the pulse method. Through the analysis of the experimental results, calculations were made for switching pulse and for the well velocity. The shape of the switching pulse at low field can be explained by the one dimensional growth of domains after the nucleation of new sites at an earlier time of switching. The sideways well velocity can be described by an exponential law of the type, v=v∞exp(−δ⁄E). The wall velocity was about 0.1 cm/sec for about 150 v/cm at 13°C, which was the same order of that obtained by the optical measurement.抄録全体を表示PDF形式でダウンロード (620K) -

ジャーナル 認証ありWe observed the ESR signal of Cr3+ ions in triglycine-sulphate. It is found that a pair of lines gradually approach to each other with increasing temperature in the ferroelectric phase and converge at the Curie temperature. The results are interpreted by using the concept of motional narrowing on the basis of the model of order-disorder type. The linewidth for the applied magnetic field nearly parallel to the principal axis z shows an anomalous increase near the Curie temperature. The critical exponent of the linewidth in the ferroelectric region is determined to be 0.5 in the vicinity of the Curie temperature and to be 2.0 far from the Curie temperature.抄録全体を表示PDF形式でダウンロード (616K) -

If there is no such N, the faintness index is defined as equal to infinity. A few examples are presented and discussed.抄録全体を表示PDF形式でダウンロード (464K) -

ジャーナル 認証ありX-ray Mn Kβ emission spectra of metallic manganese, MnO, MnP and α-MnS are obtained by fluorescent excitation method. A two-crystal spectrometer is used in the (1, 1) position. The Mn Kβ emission spectrum consists of a diagram line Kβ1,3, a valence band Kβ5, a non-diagram line Kβ′, etc. The general features of the Mn Kβ spectra of metallic manganese and MnP resemble each other and those of MnO and α-MnS are alike. According to Tsutsumi the origin of the Kβ′ line is derived from the exchange interaction between the electrons of the incomplete 3d shell of 3d elements and the hole of the 3p shell owing to the emission of the Kβ1,3 line, and thus some correlation is expected between the features of the Kβ′ line and the Kβ5 band. Results show the correlation between them and also support the fact that MnP has metallic character.抄録全体を表示PDF形式でダウンロード (356K) -

ジャーナル 認証ありA method of dynamical matrix determination by means of the thermal diffuse scattering of X-rays is presented. Born’s theory (Proc. Roy. Soc. A180 (1942) 397) is improved by including the correction terms due to the harmonic multiphonon and anharmonic scatterings. It is required to approach the self-consistent scattering matrix and dynamical matrix which appear in the intensity equations for the one-phonon, multiphonon and anharmonic scatterings by the successive approximation. It is shown that an application of this method is possible for sodium chloride crystal if the intensity measurement of thermal diffuse scattering is made accurately at 100 K.抄録全体を表示PDF形式でダウンロード (1448K) -

Results indicate that for three mode oscillation there may be an initial spatial distribution of population which would uniform the giant pulse from irrespective of initial field value.抄録全体を表示PDF形式でダウンロード (840K) -

ジャーナル 認証ありThe rotational motion of a rodlike molecule constrained in a potential cage in liquids is studied. This motion is considered in terms of the correlation in function ⟨Pl[u(0)·u(t)]⟩ of the molecular axis vector u. (Pl is the l’th Legendre polynomial; l=1 and 2 correspond to the vector and the tensor correlation function respectively.) The correlation functions are shown to be composed of two parts: One is due to rotational diffusion caused by variation of the constraining cage, and the other is due to rotational libration inside the cage. The correlation functions and their spectral densities are calculated for two simple types of the constraining potential: Suqare-well and harmonic. The integrated absorption intensity of a pure rotational band for polar rodlike molecules is discussed.抄録全体を表示PDF形式でダウンロード (904K) -

ジャーナル 認証ありThe first step in the physical abstraction of the biological nature may be opened with the general formulation on the molecular system in aqueous solution. The electronic state of the molecular complex in solvent can be given by the nonlinear Schrödinger equation where the local field acting on the complex is introduced in the form of the self-dependent reaction field due to the polarization of the solvent. With increasing solvent polarity the new state appears. This state is characterized as a super-charge-transfer state. Experimental confirmation for the theory can be found in Foster and Thomson’s experiments on the effect of solvent on charge-transfer complexes and in Nogami et al.’s experiments on the temperature dependence on the charge-transfer interaction. This new state is presented together with the ordinary state as the two states in the allosteric transition of proteins.抄録全体を表示PDF形式でダウンロード (1048K) -

ジャーナル 認証ありThe phase velocity of sound wave is measured as a function of electron density in a weakly ionized plasma.
The large increase of sound velocity density increased is observed, which cannot be explained by considering only the effect that electrons and ions are perturbed by the sound wave, which in turn modifies the sound wave. The increase of sound velocity can be explained consistently, if the increase of equilibrium temperature of neutrals due to the energy transfer from electrons by elastic collisions is taken into account and the stationary temperature distribution in space is assumed to be attained in finite system. The temperature of neutrals, which has not been measured, can be estimated by the experimental conditions with the aid of the heat conduction theory.抄録全体を表示PDF形式でダウンロード (752K) -

ジャーナル 認証ありNonlinear spatial evolutions of both plasma waves and beam electrons are studied in a weak cold beam-plasma system, where the validity of weak turbulent theory is violated. Externally driven single unstable wave grows exponentially until the beam electrons are trapped and begin to revolve in wave phase space. These trapped electrons continue to rotate from initial velocity bunching, to spatial bunching, to velocity bunching, and so on, causing nonlinear wave saturation at a level with ωB⁄γL∼1. Further, when the beam electrons are trapped, there appears the trapped-electron instability at the frequency of ω±ωB. At the phase of the spatial bunching, harmonics of the wave resulted from nonlinearities of the electron orbits become maximum and their power spectra up to the 5th are observed. The results agree with those predicted theoretically by a single wave model.抄録全体を表示PDF形式でダウンロード (1312K) -

ジャーナル 認証ありA theoretical study is made on a grey radiating gas flow along a semiinfinite circular pipe when the global optical thickness is large. The radiave heat transfer is assumed to be of the same order of magnitude as the convective one. Analyses are carried out up to the first two orders of expansion with respect to the inverse square root of the Bouguer number. The first order solution and the solution including the effect due to the radiation slip coincide with those of a flow those of a flow past a semi-infinite flat plate. For the flow outside the pipe, a correction is made on the solution taking into account the effect due to the wall curvature. In the flow inside the pipe, the effects due to the pressure change and the compressibility of the gas appear in addition to the effect due to the wall curvature.抄録全体を表示PDF形式でダウンロード (572K) -

Here Landau’s two-fluid model is adopted as a macroscopic continuous model of helium II, and the singular surface is defined such that the densities, the temperatures, the velocities of superfluid and of normal fluid are continuous while their derivatives have discontinuous jumps across the surface. It is proved that a new sound called the fifth sound may exist, which is a transverse sound fixed in the normal fluid. It is also proved that the theory of singular surface yields Landau’s first and second sounds and Atkins’ fourth sound.抄録全体を表示PDF形式でダウンロード (584K) -

ジャーナル 認証ありIt is investigaged in this paper that the behaviour of a gravitational field containing fewer moments is different from the behaviour of a gravitational field containing of all moments of the source. A gravitational field without mass and dipole moment possesses dual properties of being radiative and nonradiative simultaneously as it allows nonradiative motion during its radiative period. Quadrupole moment is absolutely conserved in such a field. The field becomes stationary just after appearance of the tail of outgoing gravitational pulse wave if the field contains only one moment of the source.
