Microscopic theory of normal liquid 3He

We have used the self-consistent scheme proposed by Singwi, Tosi, Land, and Sjoelander to study the properties of normal liquid 3He. By employing the Aziz potential (i.e., the Hartree-Fock repulsion plus damped dispersion with an additional parameter) and some other realistic pairwise interactions, we have calculated the static structure factor, the pair-correlation function, the zero-sound frequencies as a function of wave vector, and the Landau parameter F0s for different densities. Our results show considerable improvement over the Ng-Singwi model potential of a hard core plus an attractive tail. Agreement between our results and the experimental data for the static structure factor and the zero-sound frequencies is fairly good
