Potential scattering of wave packets — •Mikhail Fedorov — General Physics Institute, Russian Academy of Sciences, 38 Vavilov st., Moscow 117942 Russia

Scattering of electrons by a ponderomotive potential of a focused laser light is considered. Initial electron wave function is taken in the form of a wave packet. Non-stationary Schroedinger equation is solved in the approximation of small spreading of a wave packet during the electron-target interaction time. Similarity to and differences with a standard stationary theory of plane-wave scattering is discussed, as well as the conditions of a transition to the classical scattering picture.
