A first principle electron multiple scattering calculation is carried out for a two atom system to obtain total elastic scattering intensity as a function of energy. The total elastic electron scattering intensity from an amorphous material (Si) is calculated by averaging that from two atom systems. An excellent match is obtained between the calculated and experimental result. The calculation supports our interpretation of the fine structure found in the elastically reflected electron intensity and provides the theoretical foundation for the practical application of the technique in surface and interface studies.
