Contact values for disparate-size hard-sphere mixtures

Soft Condensed Matter 2009-05-22 v2 Statistical Mechanics Chemical Physics

Abstract

A universality ansatz for the contact values of a multicomponent mixture of additive hard spheres is used to propose new formulae for the case of disparate-size binary mixtures. A comparison with simulation data and with a recent proposal by Alawneh and Henderson for binary mixtures shows reasonably good agreement with the predictions for the contact values of the large-large radial distribution functions. A discussion on the usefulness and limitations of the new proposals is also presented.
