Finite-field evaluation of the Lennard-Jones atom-wall interaction constant C_3 for alkali-metal atoms
英文摘要：
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 (SD) approximation in which single and double excitations of Dirac-Hartree-Fock wave functions are included to all orders in perturbation theory.
