Microscopic Calculation of the Low-Temperature Properties ofHe3-He4Mixtures

Abstract

The effective interaction between two ${}_{}{}^3{}_{}{}^{}\mathrm{He}$ atoms in ${}_{}{}^4{}_{}{}^{}\mathrm{He}$ is obtained by assuming the ground-state wave function to be a product of pair correlations. It is used to evaluate some of the low-temperature properties of mixtures.
