Abstract
We report here the process for the evaporation of He atoms from the surface of liquid 4He. It is a particularly simple quantum process: a phonon inthe liquid with energy ħω > EB, the binding energy, propagates to the free surface where it is either reflected or gives all its energy to an atom on the surface. This energy is used to overcome the binding forces and the balance, ħω − EB, is carried away by the atom as kinetic energy.
