Abstract

The position of the reference plane z0 as well as the dipole and quadrupolar contributions to the long-range atom-surface interaction are evaluated within a simple model. The model treats the substrate as a bulk material and a selvedge, each of which has constant electronic density. The required polarizabilities of the atom are treated as one-term Padé approximants. It is then straightforward to calculate the electronic susceptibility and evaluate expressions for C3, C′5, and z0 that have been recently derived.
