摘要：

We consider theoretically an electron-impact ionization process at high impact energy and large momentum transfer in the presence of laser radiation. The target is modeled as an electron bound by a harmonic potential. Dressing of the target state by the laser field is treated exactly. Laser-assisted differential cross sections are calculated using either Volkov functions or plane waves for incoming and outgoing electrons. It is shown that even in the case of the low-frequency and weak-intensity laser radiation the effect of the field on these electrons can dramatically influence the shape of the cross sections.
