Semiclassical Corrections for Inelastic Atom-Surface Scattering from Classical Trajectories

Abstract

Consider an atom scattered inelastically from a surface and derive a formula for the exact semiclassical limit of the expectation value of an arbitrary, smooth function of the scattered atom's final momentum. The formula expresses this semiclassical limit in terms of equilibrium correlations for the atoms which compose the surface and quantities which can be calculated from classical scattering trajectories. We give numerical results for a simple one- dimensional example and compare these results with those given by the trajectory approximation. Keywords: Classical scattering trajectories, Trajectory approximation, Atomic scattering.
