Abstract

A model is proposed to explain the superfluid-film formation in dilute liquid mixtures of ${He}^{4}$ in ${He}^{3}$ . It is shown that the difference of mass between the isotopes increases the ${He}^{4}$ adsorption near the walls. Previous and new measurements are in good agreement with the model.
