Popis: | We show that existing theories which relate the helium-metal potential to the metallic surface charge density do not lead to a unique prediction for the surface charge density profile for a given experimental potential. A simple calculation of the corrugation of the attractive van der Waals potential for Cu(110) and Ag(110) shows that this is a contributary factor and that its inclusion improves the agreement between theories and also between experimental and calculated values for the charge density corrugation amplitude. |
