    A new theory of saturational narrowing in NMR is developed, by making use of the method of orthogonal operators expansion which has been reported in a previous article. A set of equations of motion for average values of dynamical quantities is exactly derived from the Liouville equation. With the aid of the equations, the absorption line shape is studied. In the case of strong saturation, the absorption line shape coincides with Provotorov’s one, provided the cross relaxation times are neglected, while the resonance frequency shift appears, otherwise.

    The influence of temperature and pressure on the recoilless fraction and the Mössbauer energy shift for the 9.3 keV transition of Kr83m is evaluated using the Debye frequency distribution of the lattice vibrations of the Kr solid. The contribution to the recoilless fraction due to the lattice anharmonicity is incorporated and the results are compared with the experiment. “Mössbauer characteristic temperature” ΘM of 42°K is suggested for the Krypton solid. A strong correlation between the recoilless fraction and the density of the solid is exhibited.

    The line shape is calculated for the infrared absorption spectrum corresponding to the transition between the upper and lower valence bands of tellurium. It is shown that the overall features of the calculated line shape and the temperature and concentration dependences of the spectrum are in fair agreement with experiments. From the assignments of the observed sharp peak and broad band, the magnitudes of the k-linear term S, of the spin-orbit splitting 4|Δ1| and of the binding energy of the acceptor state Δε are determined to be 2.67×10−8 eV·cm, 128.6 meV and 0.2 meV, respectively. To our knowledge, this value of S is the biggest among those reported so far for semiconductors.

    The problem on the decoupling of the retarded Green function is discussed in a vector space by making use of the method of orthogonal operators expansion. Usual operators are expressed by vectors and a tetradic operator such as the Liouville operator is expressed by a matrix, respectively. With these representations a new and general decoupling scheme is contrived. The utility of the scheme is testified by applying to the Heisenberg ferromagnet. At low temperatures the theory gives the correct spin wave spectrum and at higher temperatures yields a reasonable solution.

    The spin polarization of conduction electrons around a magnetic impurity is calculated for the exactly soluble model in which the z-component of the s-d exchange interaction is taken into account but the x- and y-components are ignored. The long-distance behavior is the same as the first order result obtained by Yosida, but with corrections in amplitude and phase. A fairly large discrepancy is noticed between the spin polarization and the function describing the asymptotic behavior. At the position of the impurity, the polarization is finite. It is noted that, when the exchange integral is large, a large charge fluctuation is induced and the amplitude of the spin polarization is reduced. It is shown that whether the bound state does appear or not for small values of the exchange integral, depends on the choice of the structure of the band or the cutoff of the interaction.

    The Hall coefficient and the magnetoresistance in a weak magnetic field are investigated for the impurity conduction processes based on a simplified model where the impurity potential is short-ranged. The formation of the impurity band and the modification of the intrinsic band are treated on the same footing by the Green function method. It is shown that the sign of the Hall coefficient is always electronic for n-type semiconductors irrespective of the degree of compensation. Two origins of the magneto-resistance, the Zeeman spin splitting and the Landau orbital motion, are separately calculated and both longitudinal and transverse magnetoresistances are shown to be of the same order of magnitude in the impurity band region. Numerical calculations of these transport coefficients are carried out as functions of the impurity concentration and of the degree of compensation. Intuitive discussion is made on the intrinsic nature of the impurity conduction processes. Further, the relation between the Hall coefficients in this model and in the Matsubara-Toyozawa model is discussed.

    The eigenfunctions of a two-dimensional finite 3×3 lattice of Heisenberg model (s=1⁄2) are obtained exactly with the aid of group theoretical technique and by using a computer. The eigenvalues of the anisotropic exchange Hamiltonian have been computed. The zeros of the partition function for the two-dimensional finite 3×3 lattice lie on the same unit circle in the complex magnetic field plane as those obtained in the three-dimensional finite 2×2×2 lattice. The zeros of the partition function obtained by coarse-graining of eigenvalues distribute on a line in the complex temperature plane. The thermodynamic quantities—specific heat, entropy, magnetization—has been numerically computed for ferro- and antiferromagnetic coupling. The critical index of the magnetization versus field is discussed on the basis of these numerical results.

    A calculation of the superexchange integral J in KMnF3 in made on the basis of Anderson’s theory. While previous quantitative treatments have been confined to the ‘three-orbital four-electron system’, the present work takes into account the effect due to other electrons and ions surrounding the system explicitly. It is found that this effect is by no means negligible. All integrals including many-center integrals are evaluated exactly. Covalency parameter dependence of each term which contributes to the superexchange integral is investigated. It is concluded that correct sign and order of magnitude of J can be obtained for reasonable values of covalency parameters.

    A lattice theory of melting transitions of polymers has been developed. A polymer in the crystalline state is considered to exist in a zig-zag structure, in a lattice without holes. At the melting temperature holes are formed in the lattice and the rigid molecules become flexible, exhibiting both gauche and trans conformations. The results of the theory are applied in some detail to polyethylene.

    Spin wave resonances in thin films are studied as a function of the angle between the field and the film plane in external fields above as well as below the demagnetizing field 4πM. Resonance fields or frequencies for spin wave modes are calculated by a theory in which the static equilibrium conditions and the resonance equation are taken into consideration on the basis of the surface-spin-pinning model and single-domain analysis. The theory predicts that two or three excitations of the identical mode occur when the frequency, the spin wave vector, and direction of field satisfy certain conditions. This multiple-excitation of the mode is confirmed experimentally in Permalloy thin films by employing the field modulation method at a frequency of 100 kHz.

    The spin orientation and the symmetry of the g tensor of FeCl2·2H2O are explained making use of the effective anisotropic exchange interaction between Fe2+ ions with fictitious spin s=1. The spin orientation is not any one of the principal axes of the local crystalline field. The origin of g tensor is divided into two parts: One is the contribution from one-ion, and the other is that from the anisotropic exchange interaction between Fe2+ ions.

    The magnetizations of phosphates and vanadates of rare-earth elements RXO4 (R=Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er and Yb, and X=P and V) were studied in the temperature range of 1.9°K to 630°K. There were not found any magnetic transitions between 4.2°K and 630°K for all system, while F. F. Y. Wang et al. reported some antiferromagnetic transitions for GdPO4, TbPO4 (zircon structure) and DyPO4 at 225°K, 415°K and 505°K, respectively. Below 4.2°K, TbPO4 (zircon structure) and DyVO4 showed the metamagnetic-like behaviours and seemed to have antiferromagnetic transition points between 1.9°K and 4.2°K. Above 200°K, the magnetizations of all materials followed the Curie-Weiss law. The slope of inverse susceptibility vs temperature plots suggest that the magnetic moments localized on these materials come from those of trivalent cations R3+. The nuclear magnetic resonances (NMR) of P31 and V51 in these materials were measured at room temperature. The NMR shifts of P31 were very small (−0.015%∼+0.038%) and any resonances were not observed for DyPO4, HoPO4 and ErPO4. As for the V51 NMR, no resonances were observed except for the NdVO4, which was also small (−0.053%). No arguments were made for SmPO4 and EuPO4 because of their extremely small susceptibilities.

    The emission and excitation spectra of Eu3+ ion doped in antiferromagnetic KMnF3 crystals are investigated at low temperatures. It is suggested from the characteristics of emission spectrum that Eu3+ ion occupies Mn2+ ion site. Several magnon sidebands are found in the spectrum of the emission due to (Remark: Graphics omitted.) transition. Both magnon creation and annihilation sidebands are observed. The temperature dependence of their emission intensities at very low temperature region is interpreted in term of the boson particle nature of magnon. The interacting magnons are considered to be of the resonance mode of KMnF3 host lattice. The efficiency of the energy transfer process from 4T1 state of Mn2+ ion to 5D0 state of Eu3+ ion strongly depends on temperature. This is interpreted on the basis of the assumption that the Frenkel type exciton associated with 4T1 state of Mn2+ ion is bound at the Mn2+ ion perturbed by a nearby Eu3+ ion and energy transfer takes place between these Mn2+ and Eu3+ ions.

    The broad-line NMR spectra of carbonatotetramminecobalt (III) bromide were observed in polycrystalline state at temperatures between 77°K and 383°K. It has been concluded that 1) from 200°K to 383°K the ammine groups are rotating about the Co–N axis, 2) there is no motion of the complex cation as a whole up to the decomposition point, and 3) below 90°K one of the four ammine groups in each complex becomes stationary.

    Non-local matrix elements of pseudopotential are used in the calculation of properties of simple metals; effective ion-ion interaction potential, elastic constants, axial ratio of divalent h.c.p. metals and phonon dispersion.
    In the course of the calculation, the Cochran’s G functions which give a simple expression of the total electronic band structure energy are calculated from the non-local model potential of Animalu and Heine with and without use of the effective band mass correction, and are compared with the G function that Animalu has given by the use of a local potential approximation.
    It is shown that Animalu’s G function is 2∼10 times as large as the present ones at the range of momentum transfer q=(1.5∼2.0)kf, and the present G functions give better calculated results of the above properties than Animalu’s ones.

    The transverse dielectric function ε=ε1+iε2 of graphite for the electromagnetic wave normally incident on the trigonal plane is calculated on the basis of the band structure for the far-infrared region where the effects of free carriers and the spin orbit coupling are predominant. In the absorption spectrum there appears van Hove singularity arising from the transition between the two degenerate bands near point K of the Brillouin zone split by the effect of spin orbit coupling, but no observable structures from the vicinity of point H. The plasma due to free carriers is markedly affected by the interband effect. The strength of spin orbit coupling λ33z is not determined definitely from the experiment available, but is estimated as 0.004eV (at point H) or 0.0055eV (at point K) as one of possible values.

    A dislocation arrangement in cell boundaries is set up on the basis of experimental evidences that cell boundaries deviate from slip plane by a few degrees. The internal stresses associated with this cell structure are determined self-consistently from the dislocation arrangement in cell boundaries and the motion of secondary dislocations through the cell boundaries. In this model, the primary slip system activates discontinuously in one layer of the cell structure and it forms slip lines with finite shear strain. If no dislocation annihilation occurs in cell boundaries, the flow stress increases approximately linearly with strain. The decrease of work-hardening rate in the later stage of deformation is due to the annihilation of closely spaced edge dislocation dipoles in cell boundaries by conservative climb.

    Measurements of electro-absorption of thin CdS crystals are carried out in the temperature range from 85 to 300°K around the photon energy of the fundamental absorption edge. At 300°K, the spectra show characteristics due to the Urbach-rule edge at low photon energies, while oscillatory behaviors of the spectra are observed at high photon energies. The reduced effective masses assoiated to Γ9Γ7 and Γ7Γ7 transitions in CdS are estimated from the dependence of the change in the absorption coefficient on the applied electric field. The spectra of the change at 85°K are concluded to consist of superposition of those related to A1 and B1 excitons, since the wavelengths at maximum peaks in oscillatory curves of the change of the absorption coefficient at the extrapolated zero-field are consistent to the above exciton wavelengths assigned from results of photoconductivity by Park-Reynolds.

    A new scheme of “correspondence” between the discrete energy levels of a hydrogen atom in a weak magnetic field ((n, l, m)-levels) and a strong magnetic field ((N, M, ν±)-levels) is proposed. This is a modification of Kleiner’s assumption about the “conservation of the number of nodal surfaces of the hydrogen eigenfunction” in a more reasonable form. This modification is made by taking into account the mixing of the adiabatic solutions having equal number of nodal surfaces. The fine structure of the exciton magneto-optical spectra in GaSe observed recently by Brebner, Halpern and Mooser is interpreted from this point of view.

    The infrared and far-infrared absorption spectra of β-GaSe and GaS have been measured in the temperature range from 50 to 300°K for the radiation polarized perpendicular to the c-axis in the hexagonal layer structure of these compounds. The reststrahlen frequencies measured at room temperature are 211.0 cm−1 in β-GaSe and about 310 cm−1 in GaS, respectively. In addition, the weak absorptions in the wave number range from 400 cm−1 to 750 cm−1 are identified with the multiphonon absorptions in the light of group theoretical analysis and of the experimental results on the Raman effect and on the electro-luminescence available up to date. The absorption line at 512 cm−1 and band around 450 cm−1 in β-GaSe are explained in terms of the localized mode of lattice vibrations induced possibly by an oxygen impurity. This analysis is the first preliminary investigation on the localized mode in a diatomic crystal of hexagonal structure.

    The behavior of carriers trapped around doped Ti ions in VO2 is investigated by means of the electron spin resonance in a temperature range between liquid nitrogen and room temperature. The line shapes are examined for different concentration of Ti. At lower concentration well resolved hyperfine lines are observed and a broad background line is superposed to them. With increasing impurity concentration, however, the single broad line grows up and the hfs lines diminish. At higher concentration only a single broad line of the Lorentz type is observed. The temperature dependences of the linewidth and the intensity for the hfs and broad lines are measured. The width of the broad line which does not vary at low temperature starts to increase at a temperature above which the intensity deviates from the Curie law. The motion of carriers localized around Ti impurity centers is discussed from these results.

    Effects of KNO2 added to KNO3 fused crystals on the phase transitions were studied. It turned out that the addition of 3 mol % KNO2 makes the phase III (ferroelectric phase) unstable, which is consistent with the conclusion from γ-ray irradiation study. With the advantage of absence of the phase III the possibility of growing KNO3–KNO2 single crystals by a double Bridgman method was examined. Transparent crystals were obtained successfully.

    Periodic atom displacements in the long period ordered alloy Cu3Pd(α″) with the one-dimensional anti-phase domain structure have been investigated by X-ray diffraction using an alloy single crystal. It has resulted from the crystal structure analysis, that in Cu3Pd(α″) the heavier atoms (palladium) are displaced toward the anti-phase boundary and the lighter atoms (copper) away from it, giving rise to puckered planes. These behaviors are different from those of Au3Cd and CuAuII in which the heavier atoms are displaced away from the boundary and the lighter atoms toward it. Thus, the atom displacements are affected by the kind of alloys. A little disordering is present in atomic sites in the mixed plane facing the boundary.

    Interstitial order-disorder transformation regarding oxygen atoms dissolved in alpha-titanium has been studied by neutron diffraction on single crystals in the range from 17 to 28 at% O. Occupation probabilities of the oxygen atoms in the octahedral interstitial sites are determined quantitatively with the variation of composition and temperature. The change of the long-range order with increasing temperature reveals a two-step process attributed to the disordering of the oxygen atoms. The static displacement of the titanium atoms parallel to the c-axis increases almost linearly with the oxygen concentration. The results are compared with the previous works in Parts I, II and III.

    By using a differential type filter the integrated intensity ratios of electron diffraction ring patterns are measured for NaCl, CuCl and BiOCl films. It is observed that these intensities gradually approach kinematical values as the filter potential is increased to values larger than several hundreds electron-volts. This tendency is the same as in the case of Au, Ag and Al films. A method for obtaining the kinematical intensities from the experimental plots is proposed.

    The absorption spectra of EuAlO3 were measured in the frequency range, 17100–21500 cm−1, in which the transitions from the ground state 7F0 to the Stark components of the three lowest excited multiplets of 5DJ(J=0, 1, 2) states were observed. The spectral lines were assigned to the transitions to the crystalline-field split components of 5DJ(J=0, 1, 2) of Eu3+ ions with the Cs site symmetry. The crystalline field analysis of these lines was made by assuming the approximate site symmetry C2v. The observed linewidths are 3–5 cm−1 at 1.9°K and much broader than those in dilute YAlO3:Eu3+. Furthermore, some of the lines seem to have two components with comparable intensity. The sources of these additional broadenings and structures of the lines are discussed. Many sharp and weak satellites were observed near the main lines. The origins of these satellites are also discussed.

    In this paper a recent variational solution of the Thomas-Fermi equation for atoms given by Csavinszky is used to calcultate certain physical quantities analytically. The results are compared with those obtained on the basis of the unmodified TF Model and the Tietz approximation. It is shown that Csavinszkys’ solution—in which the density has the right behaviour at large distances—leads to substantial improvement over the usual TF results.

    When the “solvent effect” is taken into account, it is possible to identify that the first π–π* transition by theoretical calculation lies near 2800 Å for poly (A+U) and poly (A−U).
    The sum of the oscillator strength obtained from the measurement was plotted in order to compare with the value calculated theoretically and also to see the possibility to apply the sum rule for the analysis of the electronic structure of polynucleotides. This analysis suggests that the polynucleotides have a very strong absorption band in the higher energy range than 10 eV.

    Weighted mean errors are defined and proposed as criteria of the error in an approximate wave function for an arbitrary state. Upper and lower bounds on the weighted mean errors are derived, and properties of and relations among the bounds are discussed. The Eckart and the James Coolidge criteria are shown to be special cases of some of the bounds.

    By using the close-coupling method, differential cross sections are calcultated for the vibrational excitation v=0→1 of CO by electron collisions. First, the dipole interaction is considered to be responsible for the vibrational transition and the result is compared with the Born calculation. It is found that the Born result agrees well with the close-coupling calculation in the region of small scattering angles (\lesssim30°), although the agreement is rather poor for the total (integrated) cross section. Next, the effect of the target polarization is investigated. Finally, the angular dependence of the vibrational cross section is evaluated by taking both the dipole and the polarization interactions into account simultaneously and a comparison is made with experimental data. For a small-angle scattering, good agreement is obtained for the theoretical and experimental cross sections, while they differ significantly from each other in the region of large scattering angles.

    A theoretical analysis of the ionic transport across a membrane is given in order to explain the experimental fact that the ionic conductivity through the artificial bimolecular layer of lipid molecules increases with the concentration of either cationic or anionic surface active agent in the electrolyte solutions on both sides of the membrane.
    The adopted model is the thin symmetric membrane with electric double layers whose charges are affected by the physical adsorption of the agent.
    This model is not only more realistic as a model of the lipid membrane than that used in the previous paper but also able to explain well the experimental results.

    Dependence of various quantities (rotational transform angle, shear, magnetic well depth) of average minimum B field of stellarator type on the geometrical parameters of the current configurations and the possible ranges of the values of these quantities are studied. These results are compared with computed ones.
    A condition on the Larmor radius of ion and the rotational transform angle is obtained for the smallness of deviation between drift surface and the magnetic one.
    The effects of geometrical errors of the current configurations on the magnetic surface are analysed numerically and a tolerance limit of error is deduced.

    Based on the linearized approximation to Einstein’s equation, gravitational energy losses and their spectral decompositions are calculated for the two-body system interacting each other through Newtonian force. These calculations are analogous to synchrotron radiation from an electron in the Coulomb field or a magnetic field.
