Calculated Low-Energy Electron-Diffraction Intensities for (111) and (110) Surface of Al

Abstract
Reflected low-energy electron-diffraction spectra are calculated for the (111) and (110) surfaces of Al using the band-structure-matching approach without taking into account inelastic effects. The main effort was put into the calculation of a realistic pseudopotential (no adjustable parameters). The results are compared with experiment and found to be in over-all agreement with respect to the widths and positions of the peaks, provided we identify a single experimental peak with a group of calculated ones.
