Approximate analytical expression for the direct correlation-function of hard discs within the Percus-Yevick equation

By M. S. Ripoll and Carlos Fernández Tejero


A simple approximate analytical expression for the direct correlation function of a hard-sphere fluid in D dimensions within the Percus-Yevick equation is proposed. The approximation exactly reproduces the well-known results for D = 1 and D = 3, while for D = 2 it compares well to the numerical results for densities not very close to the freezing density
