Sticking coefficient of light particles on surfaces.

Abstract

We consider a theoretical treatment of particle-surface scattering in which the sticking coefficient and scattered intensities are simultaneously calculated to arbitrarily high orders in perturbation theory. We present model calculations through third order in perturbation theory, including all two-phonon contributions, for the cases of ${\mathrm{H}}_{2}$ and ${\mathrm{D}}_{2}$ interacting with a Cu(100) surface and the case of Ne interacting with a Ru(001) surface. The direct scattering into the bound states gives rise to structure which can be observed both in the sticking coefficient and in the specular intensity.
