We perform a systematic study of the electron momentum distribution symmetry properties in electron–atom scattering assisted by an orthogonally polarized two-color laser field. We show that the dynamical symmetry of the field is imprinted onto the electron momentum distribution. In addition to the direct electron scattering off the atom, which we call the single scattering, we consider the case of rescattering where the laser field-driven electron returns and rescatters off the atom. We pay a particular attention to the role of the relative phase between the laser field components. In the single-scattering case, we identify additional symmetry properties arising from the laser field configuration. Furthermore, using the stationary phase method we derived energy conservation conditions, both for single scattering and for the rescattering. With the aid of these conditions, we assess the position of the cutoff electron energy and investigate its dependence of the laser field parameters. Our results demonstrate that the laser field parameters allow independent control of the single-scattering and rescattering plateaus. For some configurations, the rescattering plateau extends to significantly higher energies than for the single scattering.
