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 ezxpression for the qoadrupole moment of an atom in the vicinity of a perfect metal& surface is \_&en for the first time. The retardation effects are taken into account and the near-zone (London) and the far-zone (Casimir) limits of this result are considered. A numerical evaluation of the atomi
