Recoil saturation of the selfenergy in atomic systems
Abstract
Within the framework of the general selfenergy problem for the interaction of a projectile with a manybody system, we consider the dispersion force between two atoms or between a charge and an atom. Since the BornOppenheimer approximation is not made, this is a useful approach for exhibiting nonadiabatic effects. We find compact expressions in terms of matrix elements of operators in the atomic displacement which are not limited by multipole expansions.
