ABSTRACT
The impulse approximation of laser-assisted charged-particle scattering is discussed and compared with the Kroll-Watson approximation. We focus on critical geometrical scattering conditions where the exchange of photons is classically forbidden. The δ-shell model potential is used to study a selection rule which predicts that the exchange of an odd number of photons is forbidden in a geometry with the laser polarization vector perpendicular to the scattering plane. We also consider laser-induced resonance electron scattering in a geometry with the laser polarization almost perpendicular to the electron momentum transfer. Numerical simulations indicate that the so called Jung-Taylor conjecture is satisfied in the impulse approximation. © 2000 American Institute of Physics.
