We present an algorithm for the symbolic computation of the pair-distribution function g(r) for arbitrary r-values of a one-component hard-sphere (HS) system within the Percus-Yevick approximation and of a hard-sphere Yukawa system within the mean-spherical approximation (MSA). The algorithm itself

โฆ Synopsis
The pair distribution function and equation of state of a hard-sphere fluid are calculated for seveIltl modifications of the Percus-Yevick (TY) theory by means of a perturbation calculation in which the zerothorder term is the PY result. Even in first order, this technique provides a very simple way of esamining modifications of the PY theory and yields accurate results fcr low and moderately dense (po3 s 0. S) _ hard-sphere fluids.

We consider a range of integral equation theories for a simple fluid with a pair potential of the type that arises for fused-hard-sphere molecular fluids in the RAM perturbatron theory. The potential is of finite range with a finite intercept at contact, and is everywhere repulsive. Results based on
