Abstract
The energy and angular distributions of desorbed adatoms, and the temperature dependence and absolute magnitude of the desorption rate, are studied numerically within a three-dimensional quantum treatment of desorption. Model parameters appropriate to Ne adsorbed on Xe-covered graphite are employed. The angular distribution is found to peak strongly in the forward direction, and the energy distribution peaks strongly for final adatom energies near to zero. The temperature dependence of the rate is found to vary as , with a prefactor ∼ .
