Optical absorption spectra in the incommensurate sinusoidal spin-density-wave in chromium are calculated with a one-dimensional two-band model where the difference of the Fermi momenta of the two bands is taken into account. Three absorption peaks are found to appear, originating from the formation of energy gaps. For these peaks, the energy positions, line shapes, relative intensities, and the changes of these quantities by alloying with Mn are investigated both analytically and numerically. It is shown that the results are in good agreement with experimental observations. Main features of the results are shown to remain unchanged, when a more realistic model of octahedral energy surfaces is used.

A concept of a sum rule applied to the conduction electron subsystem in metals is discussed in connection with the optical conductivity and the Nozières-Pines sum rules, with the emphasis on an essential role of the Pauli-forbidden transitions of a conduction electron to occupied core states. Obtained restricted sum rules are useful means of optical analysis for metals with strong conduction-core optical coupling, and are applied to the absorption data for alkali metals. The experimental fact that the saturated values of the effective number of electrons per atom contributing to conduction electron absorption exceed the valence is interpreted satisfactorily in terms of a contribution of the Pauli-forbidden transition to the outermost
p-core state.

4Eg(

2+: KZnF
3 and RbMnF
3, is investigated theoretically. The energy level scheme including the Davydov splitting is obtained and the magnetic dipole selection rules are derived for an arbitrary applied magnetic field and an arbitrary direction of the magnetization.
Theoretical results agree quite well with experimental results for RbMnF
3. Spin-orbit interaction plays a very important role in determining the behavior of
4E exciton in the magnetic field when the spin axis rotates due to the applied field. The effective exciton transfer integral between Mn ions of a nearest neighbor pair in the paramagnetic state is estimated to be 32.3 cm

kF and ρ

L0 is the thickness of the metal. In calculation of ρ
i, the sum of wave functions over a quantum number is approximated by an expansion formula for summation of trigonometrical series but not by the usual integration over the

The validity of the “grouping method” has been examined critically; the method was contrived by Kiritani in treating an enormously large number of simultaneous differential equations which represent the clustering process of quenched-in vacancies. The method is applied to a model problem which can be solved rigorously. Size distributions of clusters at the completion of a reaction are derived by the exact and the grouping methods; when calculated with the latter method, the distribution becomes broader and the position of the maximum shifts to lower sizes. Thus, it is concluded that, at least for the present model problem, the grouping method is not valid.
By the grouping method one attempts to obtain an average of many differential equations. It seems difficult to justify such a procedure mathematically.

Variation of flow stress in pure lead at the superconducting-normal (S–N) transition is analysed on the same model as used in a theory of work hardening proposed by the present author. In this model deformation proceeds by successive activations of discontinuous slips and each unit slip produces a finite elongation in the specimen during its life time. The change in the drag coefficient for dislocations at the S–N transition changes the number of discontinuous slips to be activated in the specimen; this change in the number of slips is similar to the case of a strain-rate change. It is concluded that the plastic response of pure lead at the S–N transition is essentially the same as that at a strain-rate change.

Basing upon this method, the total energy of this system and the number of bose-condensed excitons are calculated as a function of the total concentration of excitons, and we show how the boson like character of Wannier excitons is reflected on the emission spectrum from this system and on the absorption spectrum in the presence of these excitons at finite density.

The present paper has the dual purposes. As the first purpose, it is demonstrated that the boson description of Wannier excitons introduced in the preceding paper is suitable also to discussion of non-linear coherent interaction of Wannier excitons with the radiation field. The second purpose is to discuss the possibility of self-induced transparency due to Wannier excitons on the basis of the boson description by making clear the difference between a two-level atomic system and a system of excitons which can propagate in a crystal as polariton. As a result, stable pulse propagation of the radiation field is shown to be prevented by the polariton effect of excitons.

It is shown that the quenching effect of the dipole moment and the effect of the exciton-exciton interaction modify the dispersion curve significantly. The possibility of the self-induced transparency of a pulse wave is examined by taking into account the polariton effect, and a negative answer is obtained.

The diffusion phenomena in plasmas with low charged-particle densities, in which the quasi-neutrality condition cannot be applied, are investigated with the aid of diffusion equations and the Poisson equation. From the asymptotic analysis in the limits of high and low densities, it is found that the transition between the ambipolar diffusion and the free diffusion is classified into three types. In each type, numerical solutions are obtained and the variations of the column thickness, the wall potential, the leak current to the wall, etc. with the change of the electron density are shown. When ions diffuse faster than electrons in a strong magnetic field, it is found that the electron diffusion is most enhanced in the transitional state. It is also shown that this phenomenon has influence upon the relation between the longitudinal current and field in discharge column.

Plasma parameters such as density, temperature and traveling velocity can be controlled by changing the charging voltage of the capacitor bank for the gun and the strength of the uniform field. The loss rate of the transverse energy of a plasma stream is proportional to the so-called Bohm diffusion rate for both deuterium and helium plasmas.

k·
B=0, are considered. The stability condition with
k·
B→0 differs from the condition with

B=0. For small

The electron cyclotron damping of the Bernstein waves propagating obliquely to a static magnetic field is studied.
It is observed experimentally that the attenuation of these waves becomes very strong as soon as the angle of propagation to a static magnetic field departs appreciably from 90°, (
k||\
eweq0), and the wave frequency ω approaches the electron cyclotron frequency ω
c, hence this increase of the damping is confirmed to be due to the electron cyclotron damping. The observed electron cyclotron damping arises from the resonance electrons whose parallel velocity
vr(=(ω−ω
c)⁄
k||) is several times as large as the thermal velocity of electrons
vt, and becomes stronger as
vr approaches
vt. Further, existence of these resonance electrons is clarified more clearly by injection of an electron beam. The increase and decrease of the damping occur by the electron beam whose velocity is, respectively, rather smaller and larger than
vr.

New types of sideband instabilities associated with a large-amplitude whistler wave propagating parallel to an external magnetic field
B0 are proposed and investigated. The instabilities are due to a spiral beam consisting of resonant particles of small velocities,
v⊥, perpendicular to
B0. It is shown analytically that in collisionless plasmas the angles ζ between the wave magnetic field and
v⊥ of these particles, when started from a random distribution, bunch quickly to π/2. A spiral beam is formed when there exist collisions which are insufficient to destroy this phase bunching, but are sufficient to prevent any other systematic variation of ζ. Under these conditions, three different whistler modes are found unstable in the immediate vicinity of the carrier wave frequency. Their growth rates can become greater than those of previously investigated sideband instabilities if the resonance velocity substantially exceeds the thermal velocity.

An inviscid shallow rotating ocean model with linearized bottom friction is considered to determine the frictional effects on the unsteady wave motions generated in the ocean by arbitrary as well as special atmospheric disturbances. The asymptotic solution is obtained for the free surface elevation due to stationary as well as travelling wind stresses. It is shown that the transient solution decays exponentially as
t→∞ and the ultimate steady-state solution describes standing and progressive long waves propagating upstream and downstream with exponentially damping amplitude. The inclusion of the bottom friction introduces the exponential damping factor into the amplitude, and makes other significant changes in the wave-structure as well as its various properties. The resonance-type effect on the wave motions observed in a frictionless ocean model is no longer present in this frictional model.

Modulational instability of weakly nonlinear capillary waves on a thin liquid sheet with no rigid boundary is theoretically investigated. By using the derivative expansion method, a simple nonlinear Schrödinger equation for the amplitude modulation is derived from the two dimensional Laplace equation for the velocity potential. It is found from this nonlinear equation that wave trains of finite amplitude are modulationally unstable. The phenomenon of the break-up of the sheet may be due to such an instability.

It is shown that the effect due to the pulsation of low frequency can be estimated in terms of the growth rate of disturbance in an appropriate steady velocity distribution. Decreasing of the effect with increasing frequency is related to the boundary-condition for the disturbance, and the growth rate is in proportion to inverse powers of the frequency.

The scheme works well except that it needs a very large amount of computation time. It is shown that the effect of the side walls is restricted to a relatively thin layer and the central part of the cavity is almost two-dimensional.
