THE FLUID STRUCTURES FOR SOFT-SPHERE POTENTIALS VIA THE ZERO-SEPARATION THEOREMS ON MOLECULAR DISTRIBUTION FUNCTIONS

摘要

We present a class of closures specifically designed to satisfy the zero-separation theorems for the correlation functions y(r) (the cavity function), gamma(r)=h(r)-C(r) (the indirect correlation), and B(r) (the bridge function) at coincidence r=0 for soft-sphere pair potentials. The rationale is to ensue the correct behavior of these correlation functions inside the core r
