Structure and thermodynamics of two-component classical plasmas in the mean spherical approximation

Abstract

The analytic approximation applied by Gillan to a classical one-component plasma, in which short-range correlations are grafted onto a Debye-Hückel theory through a hard-sphere boundary condition on the pair correlation function, is examined in a two-component plasma over wide ranges of temperature, densities and valences. The results for the thermodynamics and the structure of these systems are in good agreement with available Monte Carlo data and generally very close to those yielded by the hypernetted-chain approximation.
