Abstract
A one-dimensional model is used to compute the rate of thermal desorption. The oscillation of the adsorbed atom with respect to the surface is described by a Morse potential, driven by the plionon field Multiphonon processes are used to compute the rate of energy transfer to the oscillator. The activation energy is found to be smaller than the desorption barrier.
