✦ Synopsis

Classical trajectory calculations of van der Waals cluster scattering from a rigid surface are presented and compared with recent experimental results on argon cluster scattering from graphite by Chltelet et al. (1992). The cluster fragmentation at surface impact is studied for different incident translational energies and can at moderate energies be described as evaporation of small particles from the parent cluster. The experimentally observed dependence of angular distributions on cluster fragment size is reproduced by the model, as well as the appearance of two components in the expenmental angular distributions.

## Abstract This paper studies the scattering of electromagnetic waves from a (local) perturbation of a fixed surface, the boundary of a given obstacle in ℝ^3^. The goal is to produce an algorithm for solving boundary value problems in the exterior of the perturbed domain solely based on the knowle
