On the Xe-Xe potential energy curve and related properties

Abstract

A simple accurate potential of the HFD-B form is presented which appears to be the best characterization of the Xe-Xe interaction to be constructed to date. It reproduces, within experimental error, such dilute gas macroscopic properties as virial coefficients, viscosities and thermal conductivities over a wide temperature range. It also predicts, within experimental error, such microscopic properties as differential cross sections, high energy beam data, the glory structure in the total cross sections and the vibrational spacings of the Xe dimer. Moreover, it predicts the binding energy of the solid at 0 K.
