Eikonal approximation in atom-surface scattering: Effects of a corrugated attractive well

J. R. Manson, K.-H. Rieder
2000 Physical Review B (Condensed Matter)  
The eikonal approximation, which is an extremely useful method of calculating intensities for the scattering of atomic beams from surfaces, is extended to include a periodic corrugation of the leading edge of an attractive square-well potential placed in front of the hard repulsive wall. This provides a method for estimating small effects of corrugation of the attractive physisorption potential on the diffraction spectra. Calculations indicate that the relative phase of the attractive well
