Multiproperty empirical interatomic potentials for ArXe and KrXe

Abstract

Crossed molecular beam measurements of elastic differential cross sections (DCS) for the scattering of Ar and Kr by Xe are reported. Empirical multiparameter M3SV interatomic potentials for the ArXe and KrXe interactions are determined by simultaneously fitting the DCS, the viscosities, and virial coefficients; the results are the most accurate potentials yet reported for these systems.
