Abstract

The interaction between an atom and a phonon is evaluated at a surface. The basic assumption is that the total potential energy of the atom V(r) can be written as the sum of pair interactions w(r-r_i with individual substrate atoms. The result is an expansion in phonon wavevector q, with coefficients expressed in terms of the equilibrium adsorption potential. The coupling can be utilized in calculations of kinetic and equilibrium properties of adsorbed atoms.
