✦ Synopsis

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 a corrected form of the hypernetted cham theory are excellent and are supertor to all others.

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
