Inverse temperature expansion of some parameters arising from the solution of the mean spherical approximation integral equation for a Yukawa fluid

Abstract

Analytic formulas, within the mean spherical approximation, are given through fifth order for the inverse temperature expansion of the energy and the pair correlation function at contact for a fluid whose molecules interact via a Yukawa potential with a hard core. This series converges rapidly if the Yukawa potential has a long range. Reliable results are obtained from this series even when the potential has a short range.
