Abstract
The theory of the desorption of atoms is discussed for systems with general interatomic potentials and a method is given for the calculation of the rate of desorption. It is shown that for realistic potential interactions a transit time for atoms within the potential wells should be included in the expression for the desorption rate. For a one-dimensional harmonic model, this time has been determined by calculating the time-dependent desorption probability. At small times, the desorption probability shows considerable deviation from the exponential decay observed at large times.
