✦ Synopsis

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 /3 is "optimized" for a given incident energy (E,) and incident angle (0,) so as to reproduce the experimental results. An empirical expression for the softness parameter/?(E,, 6,) is obtained. Our results are in good agreement with previous calculations and experimental observations.
