Mott scattering in a field of two pulsed laser waves

Laser-modified Mott scattering in a field of two unidirectional pulsed waves is considered. The primary object of research is the cross section distribution of the final electron energy at a fixed geometry of the scattering process. The parametric interference effect is manifested within the plane formed by both the direction of the laser-wave propagation and the initial electron momentum (the interference region). The induced processes of the correlated emission and absorption of external-field photons are preferred in the interference region for the circular polarization of both laser waves. A comparative analysis of the electron energy spectra is provided in the interference region and the region where the parametric interference effect is hardly manifested, at the same parameters of a laser field and the initial electron energy. The cross section of laser-modified electron-nucleus scattering at the specified final electron energy in the interference region may be one order of magnitude greater than the cross section at the other geometry of scattering.
