Abstract
The classical expressions for kinetic theory cross sections which are related to the Senftleben-Beenakker effect on viscosity, diffusion, conductivity and thermal diffusion are evaluated using the HFD1 surface (R. Fuchs et al. (1984)) in the temperature range 77.3-1100K. The depolarised Rayleigh scattering and rotational-relaxation cross sections are also obtained. Comparisons with experiment show that the authors' values for these cross sections are 10-80% larger than the measurements. These consistent discrepancies suggest that this potential surface is too anisotropic.Keywords
