As an application of the general theory given in the previous paper1), distorted wave Born approximation calculations on the depolarized linewidths for H2 and D2 systems are presented. An assumed square well model for the spherical potential and dominant P2 and quadrupole-quadrupole nonspherical...

For a polyatomic gas simple expressions have been derived for the thermal conductivity as well as for the variation of the thermal conductivity as a function of an external field. This has been achieved by using the total heat transport as a trial function in the kinetic theory instead of the...

The effective kinetic cross sections governing the magnetic field influences (Senftleben-Beenakker effects) on viscosity, heat conductivity, diffusion and thermal diffusion as well as flow birefringence and the collisional broadening of the depolarized Rayleigh line have been evaluated for HD...

The current induced Kerr effect in the presence of a homogeneous magnetic field is treated for binary mixtures of neutral molecules and ions. The starting point is a system of moment equations derived from the linearized Waldmann-Snider equation. The dialectric tensor is calculated and studied...

Noninteracting rigid spheroids are considered which are suspended in a homogeneous turbulent flow. A renormalized expansion is used to derive a kinetic equation whose coefficients are determined by the Lagrangian correlation function of the turbulent velocity field and by the translational...

For a system of noninteracting spheroidal Brownian particles a Fokker-Planck equation is derived which takes into account a hydrodynamical coupling between translational and orientational degrees of freedom. With the moment method, transport relaxation equations are obtained from which an...

A system of noninteracting nonspherical Brownian particles with dipole moment parallel to the symmetry axis is studied in the presence of an external homogeneous electric field. A generalized Fokker-Planck equation is introduced which takes into account anisotropic translational and rotational...

The two ab initio vibrotor potentials of H2−He previously published by Meyer, Hariharan, and Kutzelnigg have been composed in one potential grid. After using this potential in close coupled scattering calculations we have subsequently obtained rotational relaxation cross sections for para- and...

For stable systems the heat conduction due to the charge carriers in a weakly ionized plasma of electrons, ions and neutral atoms is studied in the presence of a strong external magnetic field. A kinetic theory description is given in terms of transport-relaxation equations derived from the...
