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

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
Using a simple functional relation the distribution of the times of free flight in 2 claskal gas of hard spheres is shown to depend only on two specific combinations of the molecular and th~mo&ynamic parameter. This distribution has been c&u&d with molecular dynamics for three values of the density.
We calculare with molecular dynamics the distribution of free flight times for a system consisting of hard spheres in two and three dimensions In both cases the density is chosen just below the density where a phase transition can be ob served and the flight time distribution is subdivided according
