Abstract

By solving a microscopically based set of coupled Euler-Lagrange equations we calculate the optimal radial distribution function and the associated optimal Helmholtz free energy for superfluid **4He at non-zero temperatures and given density. The results on the pressure-density relation are discussed and extended to describe the normal phase of **4He, particularly, to determine the gas-liquid critical data.
