Crossed molecular beam measurements of the total differential cross sections (DCS) for the scattering of Ar and Kr by SF/sub 6/ are reported. Using anisotropic multiparameter M3SV potential forms and the infinite order sudden approximation (IOSA) to do the scattering dynamics, we determine anisotropic intermolecular potentials by simultaneously fitting the DCS, viscosities, and virial coefficients. Substantial anisotropy is required to fit the observed damping of the rainbow oscillations in the DCS. The results are the first good intermolecular potentials for the ArSF/sub 6/ and KrSF/sub 6/ interactions.
