SOLUTION OF THE ORNSTEIN-ZERNIKE EQUATION IN A HARD-SPHERE YUKAWA LIQUID CONTAINING AN ARBITRARY-SIZE HARD-SPHERE - A SIMPLE MEAN-SPHERICAL-APPROXIMATION SOLUTION AND FREE-ENERGY OF FORMING A CAVITY

The simple mean-spherical-approximation solution of the Ornstein-Zerni ke equation in a hard-sphere Yukawa liquid containing an arbitrary-siz e sphere is presented. The surface density of liquid particles on the sphere is expressed in terms of a simple function of a set of paramete rs. On the basis of this density expression, the work of forming a cav ity from the point cavity in the liquid is calculated, and expressions for the pressure, the surface tension and the Tolman length are obtai ned.
