| Abstract: | The effect of magnetic fields on collective properties of polyatomic gases has been extended outside the hydrodynamic regime. The calculations are based on a linearized Waldmann-Snider equation. The Waldmann-Snider collision operator is truncated yielding a finite matrix equation. The resulting matrix equation is solved on a computer to yield the polarized and depolarized light scattering spectra. These spectra are calculated in the absence and presence of a magnetic field. For long wavelengths it is found that the magnetic effects are of the same order of magnitude as in the Senftleben-Beenakker effects. For shorter wavelengths the effects disappear due to Doppler effects.This work was supported by NSF GP22881.Alfred P. Sloan Foundation Fellow.NIH Predoctoral Fellow. |
