Abstract

A method for interpolating between the (F)HNC and (F)PY approaches in order to take into account elementary contributions has been presented in two preceding papers concerned with the properties of zero-temperature quantum fluids, described by short-range correlated wave functions. In the present paper, both for Bose and for Fermi systems, the technique is extended to the case in which the two-body radial distribution function contains a long-range tail, going asr −4. The results obtained for the energy per particle and momentum distribution of liquid4He, polarized hydrogen and3He are presented in correspondence to variational wave functions containing only two-particle correlations.
