INVERSE TEMPERATURE EXPANSION OF SOME PARAMETERS ARISING FROM THE SOLUTION OF THE MEAN SPHERICAL APPROXIMATION INTEGRAL-EQUATION FOR A YUKAWA FLUID

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. © 1995 American Institute of Physics.
