Phase coherent control in electron-argon scattering in a bichromatic   laser field
  We study the elastic scattering of atomic argon by a electron in the presence of a bichromatic laser field. The numerical calculation is done in the first Born approximation (FBA) for a simple screening electric potential. With the help of numerical results we explore the dependence of the differential cross sections (DCS) on the relative phase between the two components of the radiation field and discuss the influence of the number of photons exchanged on the phase-dependence effect. Moreover, we also discuss the numerical results of the DCS for different scattering angles and impact energies.
