Superfluidity in Thin 3He-4He Films

Abstract

Third-sound resonance experiments1,2 have shown that the superfluid helium film can be studied with remarkable precision. In a series of experiments to study the effect of 3He on a 4He film of constant thickness we have observed several qualitative changes in the propagation of third sound.
