Nonadiabatic Long-Range Forces

Abstract

A general expression is obtained for the leading long-range correction to the static interaction of a slowly moving charged or neutral system at a large distance from a spherically symmetric atom, and precise estimates are presented of the magnitude for the systems H, $\mathrm{He} (1^{1}S,2^{1}S, \mathrm{and} 2^{3}S)$, Ne, Ar, Kr, Xe, ${\mathrm{Li}}^{+} (1^{1}S,2^{1}S, \mathrm{and} 2^{3}S)$, Li, Na, K, Rb, Cs, ${\mathrm{H}}_{2}$, ${\mathrm{N}}_{2}$, and C${\mathrm{H}}_{4}$.
