Interaction potentials for He–HF and Ar–HF using the Gordon–Kim method

Abstract

Interaction potentials computed by the method of Gordon and Kim are presented for the He–HF and Ar–HF systems. Results are given at five angles and five HF distances for 12 He–HF separations and 14 Ar–HF separations, spanning both the shallow attractive well and part of the repulsive core in each case. Agreement with variationally determined results for He–HF reported previously is very good and similar accuracy is expected for the Ar–HF results. These potentials should therefore be suitable for scattering calculations.
