Electron-hydrogen collisions in a laser field. (Reannouncement with new availability information)
The Floquet treatment has already been successfully employed (Chu, Potvliege and Shakeshaft) in calculations of laser-induced multiphoton ionizations, where it provides dressed states for an atom in a laser field. The (perturbative) dressing of target states can have important consequences in laser-assisted scattering was illustrated by Byron and Joachain. These dressed states are useful, not only for laser-induced phenomena, but also as a collisional basis set for laser-assisted collisions. In this role they are in fact very appealing, since the Floquet treatment naturally lends itself to a time-independent analysis, and hence are compatible with present field-free scattering theories. Despite the apparent applicability of this approach, work along these lines has only just recently appeared (Sharma and Mohan, Smith and Flannery, Burke et al). Byron and Joachain have illustrated that perturbative dressing of the target states can have important consequences in laser-assisted scattering. Floquet dressing however provides a more complete description (Smith and Flannery).
