Abstract : Characteristics of a classical two-dimensional (2D) model of atomic scattering from finite temperature, elastic solids are compared to similar characteristics of 'quasi-1D' scattering models in light of pertinent experimental scattering studies of rare gas atomic beams on metals. The 2D finite-range interaction field is composed of additive Lennard-Jones pairwise potentials. Compared scattering characteristics include beam directivity and position as well as variation of mean tangential/normal momentum with scattering angle. (Author)
