M. Marinescu et al., RETARDED LONG-RANGE POTENTIALS FOR THE ALKALI-METAL ATOMS AND A PERFECTLY CONDUCTING WALL, Physical review. A, 55(2), 1997, pp. 1530-1532
The retarded long-range potentials for hydrogen and alkali-metal atoms
in their ground states and a perfectly conducting wall are calculated
. The potentials are given over a wide range of atom-wall distances an
d the validity of the approximations used is established.
