Abstract
An iterative perturbation scheme is constructed for LEED calculations. The subplanes comprising an ideal crystal surface are assigned a definite order and it is shown how to calculate the scattering amplitude to any order in reverse scattering. This method can be used without supplementation by other methods when there are several inequivalent subplanes in a surface layer and has great advantages of speed and low core storage requirements. The scheme is tested by calculations on Ni(111) layer.Keywords
