Abstract

Effects contributing to an observed expansion in the lattice constant of a Xe monolayer on Ag(111) relative to bulk Xe are calculated or estimated. The major effects are the differences in geometry for the lattice sums of the pair and triple-dipole potentials and the lateral interactions of monolayer adatoms through the substrate, which is treated as a continuum. The effects included account for approximately two-thirds of the observed expansion. Presumably the remaining one-third arises from forces depending on details of the electronic structure of the adatom-metal complex.
