Abstract

We have studied desorption from a 4He film due to a hot but low-intensity beam of phonons incident from a sapphire substrate. Time of flight spectra of the desorbed atoms revealed two distinct peaks which we attribute to direct desorption by substrate phonons and to thermalization with subsequent desorption.
