Summary

PROPAGATION OF WAVES IN SUPERFLUID HELIUM 4 AND HELIUM 3-HELIUM 4 FILMS IS CONSIDERED FOR THE CASE WHEN THE NORMAL COMPONENT OF THE LIQUID IS PARTIALLY STAGNANT AND THE EVAPORATION-CONDENSATION EFFECTS ARE LIMITED. IT IS SHOWN THAT SURFACE WAVES OF TWO TYPES EXIST. ONE IS ASSOCIATED WITH VAN-DER-WAALS' INTERACTION BETWEEN THE FILM AND THE SUBSTRATE AND THE OTHER WITH PROPAGATION OF TEMPERATURE OSCILLATIONS (FIFTH SOUND). IT IS FOUND THAT VAN-DER-WAALS' WAVE IS STRONGLY DAMPED WHEREAS THE FIFTH SOUND IS A LOW-DAMPING WAVE.
