Rare 9s ad&tom dipoles are shown to be small and uvxpnble of explaining observed uork function changes Three-body dispersion forces yield v;tlues consistent xrith the reduction in the adatom p.dr potentials; contrtbutions from adatom dipoles are negligible.

The long range part of the electric dipole momentp(R 12R13R& of three inte:acting atoms is calculated as a power series in R,T1. The terms of longest range are of the types R ,\*
We present a theoretical study of O(ka) and O(k 2 a 2 ) corrections to the dipole approximation in photoionization of rare gas atoms, where k is the magnitude of the photon wave vector and a is the radius of the ionized subshell. In the dipole approximation, the photoelectron angular distribution is
The discrepancy between the dipole obtained by Bar-Ziv and Weiss and that calculated later by Meyer and Frommhold for He-Ar is probably due to the use by Bar-Ziv and Weiss of an older potential function and to their choice of an insensitive evaluation method. Arguments in favor of the notion of the
