摘要:
We present a new model to study the dynamics of electron impact ionization of atoms and molecules. In this model, the two outgoing electrons are both described by a Coulomb wave with variable charges Z(r) while the incident electron is described by a plane wave. The fully differential cross-section is then calculated in (e,2e) reactions for several atomic and molecular targets taking into account the post-collision interaction. Calculations are carried out for the coplanar asymmetric kinematics, and the results are compared with those from available experiments.
