Abstract
A recently developed formalism, which uses a basis set representation with localized wave functions to describe the short range gas atom-photon interaction, is applied to examine the sticking problem. A numerical self-consistent calculation of the local gas atom-photon coupling is presented for a one-dimensional model with a parameterization roughly adequate for He scattering from a transition metal surface. Based on these results a very simple Hamiltonian is constructed, which permits a solution of the transmission problem and yields sticking coefficient one for zero substrate temperature and kinetic energy of the gas atom equal to zero. The influence of the quadratic phonon coupling terms is studied for a special example.
