Abstract
The Zharkov-Silin Fermi Liquid theory of solutions of4He in non-superfluid liquid3He has been applied to the recent phase separation data of Nakamura et al. At zero pressure, the difference in binding between a4He atom in liquid4He and in liquid3He is smaller than previous estimates, and the4He effective mass is close to the bare mass. The volume measurements of Laheurte show that the difference in binding has a minimum near ∼11 atm. This implies an enhanced solubility of4He in3He below 0.1 K at this pressure, although there is experimental evidence that the solubility at 0 K remains zero.
