Phys. Rev. Lett. 46, 1461–1464 (1981)Phase Separation in Films of 3He-4He MixturesReceived 9 January 1981; published in the issue dated 1 June 1981 We report detailed observations of the propagation of third sound in 3He-4He mixture films as a function of temperature and 3He concentration. The data are consistent with a simple model for the film and we conclude that thin 3He-4He mixture films exhibit nearly complete phase separation. © 1981 The American Physical Society URL:
