High-Temperature Quantum Corrections to the Second Virial Coefficient for a Hard-Core-Plus-Attractive-Well-Potential Model

Abstract

High-temperature asymptotic expansions of $B_{\mathrm{dir}}$ for a hard-core-plus-attractive-well potential are calculated using a method developed by Hill and reformulated by D'Arruda and Hill. To lowest order, we find the first quantum correction from the well to be independent of the shape of the well and to depend only on the value of the potential at the core.
