Abstract
A classical model of atom/surface scattering is presented in which the gas-surface interaction consists of a corrugated hard wall plus attractive square well. New analytic solutions for the scattering intensity for monoenergetic beams are given for both one- and two-dimensional surfaces. Explicit formulae for trapping probabilities and rainbow angles are obtained. An oven beam velocity distribution is incorporated into the model, and calculated results are presented both for in-plane and out-of-plane scattering. Comparisons are made with the Ne/LiF data of Smith, O'Keefe, and Palmer and with the classical calculations of McClure. Objections to the classical rainbow scattering interpretation are discussed.
