Abstract
Close‐coupling calculations of effective cross sections for transport and relaxation processes in Ar+H2 mixtures are performed, using both the recent TT3(6,8) potential of Le Roy and Hutson and the older BC3(6,8) potential of Carley and Le Roy. The cross sections calculated are those involved in sound absorption, thermal diffusion, shear viscosity, pressure broadening and shifting of rotational Raman lines, depolarized Rayleigh light scattering, nuclear magnetic relaxation, and the Senftleben–Beenakker effects. Comparisons with experimental results are made wherever possible.
