The interference effect in electron scattering on a nucleus in the field of two pulsed laser waves of circular polarization

Electron scattering on a nucleus in the field of two unidirectional pulsed laser waves of circular polarization is considered. The interference effect was detected if an electron scatters in the plane determined by the direction of laser wave propagation and the initial electron momentum. In this kinematics the electron emits and absorbs photons of both waves in a correlated manner. Broadening of partial differential cross sections is studied near the interference outgoing angle of the electron. It is shown that the partial probability of stimulated processes in the interference region may be five orders of magnitude greater than the corresponding probability of processes in any other geometry. The results may be experimentally verified, for example, in the framework of the FAIR (Facility for Antiproton and Ion Research, Darmstadt, Germany) project. (paper)
