| Abstract: | A statistical mechanical theory of the dilute mixtures of 3He and 4He is presented. It is shown that the ground state energy is proportional to the 3He density. The chemical potential expressed in terms of the sound velocity assumes the form which has been suggested phenomenologically. From the chemical potential, the effective 3He4He interaction and osmotic pressure are derived. The effective mass of 3He is also calculated as a function of potential parameters. |
