Calculation of low energy atomic diffraction (LEAD) intensities

Description

Title of program: ATSCAT Catalogue Id: ACCX_v1_0 Nature of problem Low energy atom scattering experiments (E < 200 meV) on crystal surfaces provide diffraction patterns which reflect the two dimensional periodicity of the surface and the nature of the surface-atom interaction potential. This data is compared with theoretically produced intensities in order to determine unknown surface structures or, for known surface structures, to test the validity of ab initio atom-surface interaction potentials.
