About this Item

Print on Demand. This book is a continuation of the author's previous work on the pair correlation function. It presents a solution to the first-order perturbed Percus -Yevick equation for arbitrary pair potentials of hard cores with repulsive tails, which bridges the gap between the statistical mechanics of hard sphere fluids, and fluids with continuous pair potentials. The study of the pair correlation function allows us not merely to compute thermodynamic quantities, but also to predict the structure of the fluid. The author's solution for the pair correlation function is found in the form of a series of successive density approximations. The central idea is to perturb the nonlinear P.Y. equation to obtain a linear integral equation for the first-order perturbed correlation functions, which can then be solved exactly for a general interparticle potential. The validity of the first-order perturbation theory is tested by evaluating the expression obtained for the first order direct correlation function in the particular case of a tail potential which is a replica of the core over a finite range. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book.

About this title

Synopsis

Excerpt from Exact Solution of the First-Order Perturbed Percus-Yevick Equation for Arbitrary Pair Potentials

The Ferous - Yevick approximate integral equation for the pair correlation function in classical statistical mechanics has been solved exactly for hard cores The direct correlation function is given in its non - vanishing domain by a low order polynomial, of degree one or three, for the case of one or three dimensional hard cores. Exact solutions of the p.y. Equation for potentials of arbitrary range have never been obtained, however. The object of this work is to examine the effect upon the correlation functions of adding a long-range interaction to the repulsive core. Although treated exhaustively in one - dimension, our technique is by no means limited to this, indeed being applicable to both three - dimensional non-polar and polar liquids.
