Accurate calculation of the low-energy electron-diffraction spectra of Al by the layer Korringa-Kohn-Rostoker method

Low-energy electron-diffraction spectra for three beams of Al {001} have been calculated from a complex static potential by a method of an accuracy comparable to modern band calculations. Despite the presence of strong attenuation, the spectra still show considerable structure which arises from the potential and which corresponds closely to experiment. © 1971 The American Physical Society.
