Abstract

We analyze the laser ellipticity dependence of n-photon differential cross sections (dσ_n/dΩ) for electron-atom scattering in an intense elliptically polarized laser field. We show that there exist two plateau-like structures in the dependence of dσ_n/dΩ on n for any ellipticity, including for the case of circular polarization. We present numerical predictions for e-H scattering in a CO₂-laser field and an analytical description of the plateau features in terms of the rescattering scenario.
