# Calculation of the renormalised electron scattering matrix of a molecule adsorbed on a crystal surface

## Description

Title of program: TAUMOL Catalogue Id: AAXA_v1_0 Nature of problem The purpose of this program is to evaluate a quantity required in the calculation of diffuse low energy electron diffraction (LEED) intensities from disordered adsorbates on crystal surfaces. Pendry and Saldin pointed out that such a calculation can be split into three steps: in the first all the scattering paths of the electron prior to its first encounter with the adsorbate are evaluated; in the second the paths between the electron's first encounter and its last with the adsorbate are calcula ...
