摘要：

High resolution He diffraction and bound state resonance measurements carried out with energy selection of the scattered beam from a Rh(110) surface are reported and analyzed. As for Ag(110), Cu(110) and Au(110), the lateral average of the electron density of Rh(110) is found to be in close agreement with that obtained by the superposition of atomic electron densities calculated within the degeneracy-dependent self-interaction corrected (D-SIC) local density approximation (LDA). The spread of the atomic electron densities in the surface plane exhibits behaviour similar to that observed for noble metals. The He-surface dispersion coefficient C is found experimentally to be 280 +/- 20 meV angstrom3.
