Using the close-coupling method we have investigated the diffraction of He atoms from a Cu ( 110 ) surface. Interaction between He and the copper surface is represented by a corrugated Mie-type potential. The softness parameter β is “optimized” for a given incident energy (Ei) and incident angle (θi) so as to reproduce the experimental results. An empirical expression for the softness parameter β(Ei, θi) is obtained. Our results are in good agreement with previous calculations and experimental observations.
