Using the exact close-coupling method we have investigated the diffraction intensities of He atoms from a Ag(110) surface. He-Ag(110) interaction is represented by a corrugated Mie potential. In our calculations we have used three different well depths D. Diffraction intensities were calculated for x = <001> direction. The softness parameter β is optimized for a given incident energy Ei and incident angle θi so as to reproduce the experimental results. Using well depth D and van der Waals constant C3 for six He-metal (Al, Ni, Cu, Ag, Pt, Au) systems we have obtained a relation, D = 0.070C3 − 9.006, between parameters D and C3. Our results are in good agreement with experimental observations.
