Abstract
Quantum-mechanical expressions for the potential energy of a moving charged particle interacting with a metal surface are derived using the self-energy formalism. The expressions include the contributions of the surface and the bulk plasmons in the hydrodynamic model. It is found that the saturation of the image potential at z=0 arises due to both the plasma dispersions and quantum recoil arising from the plasmon exchange and that the contributions of these two are not additive. Numerical results for the real and imaginary parts of the self-energy are presented for four speeds of the incident particle moving normal to the surface.
