The (γ,
p) reactions in fluorine and carbon were studied with bremsstrahlung X-rays of energies up to 24 MeV. Photoprotons were observed by using nuclear plates.
Energy spectrum of photoprotons from fluorine exhibits peaks at 3.8, 4.6, and 7.4 MeV which are in good accord with those observed previously by Forkman and Wahlström, and Dodge and Barber. In addition to these we found peaks at 1.9 and 2.8 and a somewhat uncertain peak at 6.1 MeV.
Angular distributions of photoprotons from fluorine showed an asymmetry around 90° with respect to the direction of incident photons, which suggests interference between absorbed photons of different parities.
In the case of carbon, a main peak at proton energy of 6.0 MeV was observed along with slight humps at 4.5 and 5.2 MeV. The observed structure is in good agreement with those reported previously.

Elastic and inelastic collisions induced by 55 MeV protons with
4He nuclei were investigated by use of the

3He, as shown in Fig. 6. The total cross section for the latter is 40 mb. The total cross section for all inelastic events were estimated from the continuum portion in the energy spectra of protons as 50–80 mb. The existence of an excited state in
4He at the excitation of about 22 MeV was indicated by searching an anomalous peak in the energy spectra of protons.

The decay of Ce
135 was studied by measuring internal conversion and singles and coincidence gamma-ray spectra. Twenty-one transitions are assigned to the decay of Ce
135. They are 205(18), 265(100), 300(55), 515.5(27), 569 and 570.5, 602(56), 661(≈9), 777(21), 821(21), 865(≈13), 901(≈8) and weak transitions of 52.4, 87.4, 117, 118, 132, 379, 544, 549 and 679, where energies are indicated in keV and relative transition intensities are written in parentheses. Coincidence pairs of 265–515, 265–602, 265–901, 300–569 or 570.5, 300–865 and 205–570 or 602 keV were found from gamma-gamma coincidences. Multipolarities of some transitions are assigned from K/L ratios and conversion coefficients. A tentative decay scheme is proposed.

The galvanomagnetic properties of thin bismuth samples have been found to exhibit some strong dependences on sample size at 77°K, involving a reduction in the transverse magnetoresistance and Hall coefficient with decreasing thickness. It has been shown theoretically and experimentally that this size-effect is related to the diffusion length rather than to the mean free path. Comparison of experiments with theory gives a value for the effective electron lifetime, τ∼4×10
−10 sec. The magnetic field dependence of the transverse magnetoresistance is also discussed.

The infrared absorption observed at low temperatures, where the wavelength dependence of absorption is like the free carrier absorption and also the magnitude is even larger than at room temperature, is explained on the basis of the direct transition of electrons from a shallow donor level to the lowest conduction band. It is shown that the absorption coefficient resulting from this mechanism is in good agreement with experiments for
n-type AlSb, GaP and Si when a reasonable value is taken for the concentration of donor electrons.
For the excess absorption observed in the above materials, the indirect transition from a shallow donor level to the conduction bands of subsidiary minima is investigated as a possible mechanism. The calculated absorption curve is shown to be very similar to that due to the interconduction band transition investigated previously.

Birefringence patterns in antiferromagnetic NiO crystals were investigated with the orthoscope and conoscope methods using a polarizing microscope. A new birefringence pattern (p-domain pattern), which differs from usual twin domain patterns in NiO crystals, was found within a crystallographically single domain in rather thick slabs. A (111) slab untwinned over 92 percent of its volume was made using Slack’s technique. The p-domain pattern in the crystal changed after application of magnetic fields above 2 kOe. The isogyer figure of single p-domain showed that the domain deformed anisotropically by 2×10
−5 along one of 〈11\bar2〉 or 〈[\bar110〉 in the (111) besides the known deformation along the [111]. The field dependence of the p-domain pattern was interpreted by regarding the p-domain as an antiferromagnetic spin domain in which the spin easy direction is one of 〈11\bar2〉 within the (111). Magnetic anisotropy measurements of the crystal were compatible with this model.

The weak field magnetoresistance coefficients and the Hall mobilities have been measured at temperatures between 77°K and 196°K on oriented single crystals of
n- and
p-type magnesium stannide having carrier concentrations ranging from 1.3×10
16 to 9×10
17 per cm
3.
The magnetoresistance coefficients of all
n-type samples satisfy very well the symmetry relations appropriate for a 〈100〉 ellipsoid-of-revolution multivalley model of energy surfaces over the whole temperature range. The energy spheroids are prolate. The value of anisotropy parameter
K=(
ml⁄
mt)·(τ
t⁄τ
l) for the purest sample is 4.2 at 142°K and decreases to 3.5 as temperature decreases to 77°K, while for the impure samples the lower
K values are obtained, indicating ionized impurity scattering effect.
The same 〈100〉 symmetry relations seem to be held for
p-type sample too at temperatures between 77°K and 169°K, although not conclusive. Anisotropy of hole band is, however, much less than that of the electron band. The value of
K is about 1.7 or 0.6 if 〈100〉 spheroid model is taken. Existence of another spherical band might be possible.

The characteristic electron energy loss spectra of Ag-Al alloy are studied at various compositions using the Möllenstedt-type analyzer with the primary electron energy of 30 KeV. The energy loss due to the plasma oscillation decreases continuously from 3.5 eV to 3.3 eV with increase of concentration of Al and varies to 14.8 eV at 70 atomic per cent Al discontinuously. The intermediate energy value of plasma excitation between 3.5 and 14.8 eV is not observed. The 14.8 eV energy loss shows always a clear dispersion, i. e. the change in energy value with scattering angle, as is the case for pure Al. The other energy loss values vary discontinuously at 20 and 70 atomic per cent of Al. The discontinuous change of plasma energy can be explained by taking account of the interaction between plasma oscillation and inter-band transition.
The energy spectra of ζ-phase (h.c.p. type) and μ-phase (β-Mn type) alloys are also observed. These spectra are quite different from the above spectra, and plasma energies of ζ-phase and μ-phase are considered to be 5.2 eV and 4.5 eV, respectively.

The antiferromagetic structure of MnHg was investigated by neutron diffraction measurements on the powder sample. The Mn atoms are arranged on a simple cubic lattice, which splits into two face centred cubic sublattices so that the magnetic moments on one sublattice are antiparallel to those on the other. The magnetic moment of a Mn atom is close to 4 Bohr magnetons. The angles between the magnetic moments and the crystallographic axes remain undetermined. The Néel point is evidently higher than 300°K, and there is no remarkable change in the neutron diffraction pattern at 198°K, where the magnetic susceptibility exhibts a distinctive anomaly and the crystal lattice undergoes a slight distortion from cubic to tetragonal symmetry.

Neutron diffraction measurements were made on Mn-Zn alloys in order to investigate the magnetic structures and the atomic superlattice structures. The following superlattices were confirmed: α′-MnZn
3 is of the Cu
3Au type, ε′-MnZn
3 of the Ni
3Sn type, and β
1-MnZn of the CsCl type. Crystallographic and magnetic structures of β-Mn
3Zn
2 are similar to thoes of β
1-MnZn. Both ε′-MnZn
3 and β
1-MnZn exhibit a spontaneous magnetization at room temperature. It seems that the former is simply ferromagnetic while the latter has an angular arrangement of the magnetic moments. An antiferromagnetic structure of α′-MnZn
3 at low temperatures is associated with a tetragonal distortion of the lattice, in which the magnetic moments in a
c-plane are parallel to each other and antiparallel to those in adjacent
c-planes.

Torque and susceptibility measurements with well annealed and chemically polished crystals of CoO were made down to 90°K. When cooled through the Néel point of 20°C with a temperature gradient along one of the cubic principal axes, the crystals yielded torque and susceptibility curves that are attributable to nearly untwinned tetragonal crystals. The torque amplitude for rotation about the axis of the temperature gradient is very small, while those for rotations about the other two axis are large; the torque does not always vanish in the directions of the principal axes, which means that the antiferromagnetic spin axis is parallel to none of them, as theory predicts. The susceptibility measured along the axis of the temperature gradient decreased with decreasing temperature, while those for the other two axes were nearly constant and equal. These susceptibilities, when extrapolated linearly to absolute zero, agreed with the theoretical values for the single-domain crystal predicted by Tachiki.

A ferroelectric 50 c/s
D-
E hysteresis loop was observed in a
c plate of NaNO
2, after the strength of applied field had once fairly been increased for a while, in spite of the fact that the spontaneous polarization of this ferroelectric is regularly in the
b direction. A microscopic observation of such converted
c plate revealed that in the major part of the region under electrodes the original
b direction had been changed to roughly definite directions inclined to all of the original three crystallographic axes. These experimental results seem to support an opinion that the polarization reversal in NaNO
2 would be realized by a rotational behavior of NO
2 radicals and suggest that the behavior of NO
2 radicals in the polarization reversal would be an unexpectedly complex one in which the three kinds of rotations around three crystallographic axes are mixed up with each other.

D=−0.0023±0.0005 cm
−1. Behavior of orientation-dependent line widths was observed and was related to the mechanism of the random internal strain. A part of weak lines at lower magnetic field was interpreted as ‘forbidden’ transitions corresponding to
ΔM>1. Transition probabilities were computed and compared with observed intensities. Some comments are offered as to the ESR study of the ferroelectric phenomenon just above the Curie temperature.

The Mössbauer spectra of Fe
57 in FeCl
2 have been measured over the temperature range of 1.5°K–530°K. The temperature dependence of the observed
e2qQ⁄2 is fairly strong. Even below the Néel temperature of 24°K, the spectra showed only two absorption lines due to the electric field gradient at the iron nucleus and did not show any typical patern of six absorption lines due to the internal magnetic field. The quadrupole splitting changed abruptly by about 30% through the Néel temperature. The parameters obtained are as follows;
e2qQ⁄2=0.80 mm/sec, δ=1.26 mm/sec at room temperature (above the Néel temperature) and
e2qQ⁄2=1.36 mm/sec, δ=1.50 mm/sec and
Hint=0±8 koe at liquid helium temperature (below the Néel temperature). These characteristic features are completely explained with the following Hamiltonian for ferrous ion in the orbital triplet;

The Wigner representation
Fs(

F(

Fs(

h\Tr
F(
p,
q)
Δ(
p−
p,
q−
q) where
Δ is a quantum analogue of a delta function in the phase space. This gives in particular the Wigner distribution function for a density operator. Basic theorems are summarized for the computation rules for quantummechanical operators in the Wigner representation. This is applied, in particular, to electrons in a magnetic field, for which a Wigner d. f. is introduced to describe the distribution of physical momenta \vecπ=
m\vec
v, \vec
v being the velocity, and the position
x. This description has the advantage to avoid the use of a vector potential and so to be gauge-independent. As examples of application, the diamagnetism and the Hall effect are briefly treated. Further applications of this treatment will be published later.

Cyclotron absorptions in
n- and
p-type PbTe recently observed by Nii are analysed under classical skin effect conditions. When the values of d.c. magnetic field corresponding to peaks are plotted against the field directions, a close fit is obtained between the calculated and observed results on an assumption of a set of 〈111〉 ellipsoids of revolution model for the both conduction and valence band extrema. From the best fit
mt=0.024
m0 and 0.031
m0 for the transverse effective masses and
K=
ml⁄
mt=9.8 and 12.2 for the anisotropic mass ratios are obtained for each band.
The observed absorption curve shows weak structures at low magnetic field. They are supposed to be due to the second harmonics of Azbel’-Kaner cyclotron resonance. However it is unnecessary to introduce other bands to explain the experimental results. The applicability of the classical magneto-ionic theory is examined by calculating the power absorption coefficient and the penetration depth as a function of d.c. magnetic field.

A system of
N identical particles is considered, which are subject to a common external field
V(
x,
y,
z) and interact with each other as given by a spinfree symmetric operator
V1.
V is assumed to be invariant against rotations of a group \mathfrak
G. When these particles are assigned to orbitals of a degenerate bound level γ of \mathscr
F, a single configuration γ
N is obtained. Interaction
V1 splits this configuration into a number of states, each of which is characterized by an irreducible representation
Γ of \mathfrak
G and an irreducible representation ∑ of the symmetric permutation group. A general formula is derived by which the number
n(
Γ, ∑) of states with representations
Γ and ∑ arising from a configuration γ
N is easily obtained. The application of this method is discussed for the following cases: (1) Russell-Saunders’ coupling of electrons in an atom, (2) Coupling of electrons assigned to a degenerate molecular orbital, or electrons in an ion subject to a strong ligand field, (3) Coupling of nucleons in a nucleus for the case in which the interaction is assumed independent of ordinary spin as well as of isotopic spin (Wigner’s case I). The method is shown to be applicable slso to the case of
j–
j coupling.

The ultraviolet absorption spectra of evaporated films of substituted
p-terphenyl show a remarkable difference from those in the
n-heptane solution; the strong peak in the solution splits into three, and two very weak peaks appear. The splittings are constant in the
p-substitution products, while they increase in the order of
H→
I in the
m-substitution products.
These facts are explained by the hindrance of large torsional motion in the crystal, and the assignments of spectra and of types of vibrations concerned are discussed.

Ionic permeability of the membrane of ion-exchange resin is investigated. The case where the exchange rate is extremely slow as in a chelating resin is treated. The diffusion equation in the presence of chemical reaction is introduced and used instead of the ordinary Nernst-Plank equation since the rate of chemical reaction is predominant in this case. The approximate solution is obtained by using the method of Laplace transform.
The concentration profiles of exchanged ions obtained as functions of time show quite a different tendency from that in the cases when the diffusion process is considered to be predominant. The result is considerably in good agreement with the experimental results on the Dowex A-1. The ionic transport processes in the presence of constant electric potential applied across membrane are also treated.

Molecular motion in three synthetic polypeptides has been examined by proton magnetic resonance methods in the temperature range 90°–430°K. The observed temperature dependence of the NMR second moment has been accounted for in terms of the motion of the side chain substituent. It becomes evident that at 90°K poly-β-benzyl-L-aspartate and poly-γ-benzyl-L-glutamate are in the rigid lattice while for poly-β-methyl-L-aspartate side chain methyl group undergoes rotation. It is concluded that the helix of the polypeptides undergoes neither rotation nor oscillation in all temperature range studied. The immobility of the helix of the polypeptides is interpreted in terms of the existence of the side chain substituent and the intramolecular hydrogen bond.

A one-dimensional model for the motion of a single excess electron or hole through the π-system in polypeptides is formulated by taking into consideration intra- and inter-monomeric electron-vibration interactions explicitly. The atomistic origins of the interactions are also investigated within the framework of the HMO SCF and the LCMO approximation for monomeric and polymeric wave functions, respectively, and their essential roles in the charge transfers are disclosed.

A theory based on an equivalent rigid ellipsoid model is presented to explain the shear gradient dependence of intrinsic viscosity of polymers such as polystyrene. An ensemble of independent coiled polymers in a dilute solution, at a
Θ temperature, is assumed to be replaced by that of hydrodynamically equivalent rigid ellipsoids with various dimensions. For each ellipsoid, one makes use of results of Saito’s and Scheraga’s theories for the non-Newtonian viscosity of ellipsoidal particles. Ratios of the intrinsic viscosity at gradients
G to that at zero-gradient are numerically computed as a function of (1.47⁄
kT) (〈
L2〉
0⁄
M)
3⁄2M3⁄2η
0G, without the aid of any other ajustable parameters. Here
M is the molecular weight of the polymer, 〈
L2〉
0 is its mean square end-to-end distance in an unperturbed state, and η
0 is the viscosity of the solvent. The result is compared with other theories and with experiments made near
Θ temperatures. An agreement between theory and data on viscosity of monodisperse polystyrene by Passaglia
et al. is satisfactory.

Maser action due to a mixing between unperturbed spin states, which is produced by a strong coherent pumping field at an angular frequency ω, is investigated by using rate equations of a spin density matrix referred to a rotating coordinate system. The relaxation of each state, which was introduced usually by phenomenological considerations, is obtained from an interaction Hamiltonian of the spin moments with local fields. The induced oscillating fields at 2ω±ω
s and ω
s, which are proportional to a small signal field at a frequency ω
s, have the possibility of power emission (or absorption) by choosing suitably the pumping field. The components at 2ω±ω
s are responsible for a frequency mixing between ω and ω±ω
s occuring in the rotating coordinates. The emitted (or absorbed) line shape is not a simple Lorentzian in the case of the spin moment 1×h and considered to be a quantum affect in the three level scheme. The frequencies of the emitted (or absorbed) fields are expected to be shifted by varying the magnitude, or the frequency of the pumping field, or the static magnetic field.

The rate of energy loss of a charged particle moving through an unstable plasma is discussed as an initial value problem under the assumption that there are no other causes of disturbances than the charge itself. The plasma is assumed to be composed of two streams of electrons. When the speed of the charge exceeds those of the streams, the stopping power tends to a finite limit, as time passes, without any influences of the instability. A steady solution is also obtained.

Ion acoustic waves propagating in a collision-free plasma at an arbitrary angle with a strong, uniform magnetic field \mathscr
B0 are investigated. The plasma is assumed to consist of two components with Maxwellian velocity distributions which have different drift velocities along \mathscr
B0. The dispersion relation derived from the Boltzmann-Vlasov and Poisson equations is studied by a graphical method developed by E. A. Jackson. Stable and unstable regions of these waves are shown to be slightly different from those of the waves propagating along \mathscr
B0. The structure of the regions is also indicated by lines of constant frequency and constant growth rate.

The equations of motion of an infinite plate performing rotatary oscillation in an infinitely conducting viscous fluid under a transverse magnetic field have been solved by expanding the velocity profile in powers of the amplitude of oscillation of the plate. The steady part of the radial and axial velocity components has been evaluated by another approximate method which includes all the terms of the inertia force. It is found that the effect of the magnetic field is to reduce the boundary layer thickness for the steady as well as the unsteady radial and transverse velocity components, and to increase the shearing stress at the plate.

In the present paper is studied a frozen region formed around a line heat sink under a uniform stream of an incompressible fluid. The diameter and the geometrical shape of the frozen region are obtained in terms of strength of the heat sink and the uniform velocity at infinity in the ultimate steady state that the system will reach. The results are compared with the experimental values given by Takashi in his practical investigation of the soil-freezing method in engineering construction.

We have found a miss in the setting of lines after the proof, and the five lines from the second line in the right-hand side of page 1136 in the text, “Matthews-Walling’s... where”, should be put in under the sixteenth line in the left-hand side of page 1137.
