Abstract
The angle-resolved thermal desorption flux for Ne-Cu(111) has been computed at 5, 10 and 15 K in the Distorted Wave Born Approximation using an accurate microscopic description of the surface lattice dynamics, and a realistic gas-solid potential. The angular distribution narrows as the temperature is lowered, being broader than the equilibrium theory cosine law at 15 and 10 K and narrower than it at 5 K. The Time-of-Flight spectra of the desorbed atoms are also analysed.
