Abstract
The band-matching approach has been used to calculate low-energy electron-diffraction intensity curves for the basal cleavage plane of beryllium. An approximation to the exact theory, made possible by the presence of strong inelastic scattering, has enabled these curves to be calculated very rapidly for general angles of incidence and with a detailed, nonlocal potential with no adjustable parameters. There is striking similarity between the calculated intensities and the detailed experimental work of Baker.Keywords
