The first part of the paper concerns the experimental determination of the two-dimensional effective interaction potential between 3He atoms adsorbed on the surface of liquid 4He. Measurements of the velocity of surface sound and of the surface tension indicate that, for concentrations of 3He corresponding to a small fraction of a monolayer, the interaction is very weak and predominantly repulsive. This is unfavorable for a low-temperature super-fluid condensation.
