Abstract

A finite-field scaling method is applied to evaluate the Lennard-Jones interaction constant $C_{3}$ for alkali-metal atoms. The calculations are based on the relativistic single-double approximation in which single and double excitations of Dirac-Hartree-Fock wave functions are included to all orders in perturbation theory.
