Abstract
We go beyond the approximate series expansions used in the dispersion theory of finite-size atoms. We demonstrate that a correct, and nonperturbative, theory dramatically alters the dispersion self-energies of atoms. The nonperturbed theory gives as much as corrections compared to the traditional series-expanded theory for the smaller noble gas atoms.
