Abstract
We consider the inelastic interaction of a neutral atomic projectile s cattering from a solid surface. Several computational models are devel oped to analyze the diffuse multiphonon component in the scattered int ensity. Through extensive numerical calculations we determine the vali dity ranges of these approximations. Comparisons with experimental dat a for He scattering from LiF(001) and KCN(001) provide examples of the applicability of these theoretical approximations.
