Nonrelativistic Kapitza-Dirac Scattering.
Abstract
The authors use techniques of Singular Perturbation theory to investigate the scattering of nonrelativistic charged particles by a standing light wave (Kapitza-Dirac scattering). Unlike previous treatments, they give explicit results for the effects of the time dependent part of the field. For low field intensity/low particle energy they show that the leading order effects can be found from an averaged equation and they compute corrections. For the strong fields that can be produced by modern lasers and/or high particle energies they show that the time dependence of the potential leads to focusing. Their methods can be applied to other problems with time-periodic potentials. (Author).
