Abstract
The influence of the angular divergence of the primary beam on the dynamic intensities in LEED is investigated. It is shown that the corresponding finite instrument transfer width restricts the area of dynamic scattering within one layer. For usual angular apertures of about 1° reductions considerably below the area determined by inelastic processes result. This reduces the lattice sum to be executed in intralayer scattering. For a typical value of the imaginary part of the optical potential, v 0 i =4 eV, changes up to a few percent of the intensity result. Hence more realistic intensity spectra are calculated with a simultaneous considerable saving of computing time.
