Energy dependence of angular momentum transfer in post-collision interaction. Classical view

A classical approach to the description of angular momentum transfer between the Auger electron and photoelectron in post-collision interaction is worked out. The results of the classical approach coincide with the quantum mechanical ones at the photoionization threshold. Besides, the approach developed provides a description of angular momentum transfer beyond the photoionization threshold. In particular, it is suitable in the energy region of comparable velocities of two emitted electrons.
