Abstract
The spin-averaged Slater sum of the fermion system is expanded in terms of the square of the ground state wavefunction of a boson system and the "antisymmetry" Ursell function. This expansion is used to obtain the cluster series for the radial distribution function of the fermion system in terms of (−C(n)/S), where C(n) is sum of chains of (−f/S) and (−fhB2/S) bonds. The series is further expressed in a more compact form using a function L(n) defined by Eq. (55), and the "modified" FHNC approximation for the radial distribution function is presented.
