Direct and thermal desorption of ^4He films

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.
