Angular distribution of ejected electrons in atomic collisions: The three-dimensional solvable model and the adiabatic approach.

Abstract

A three-dimensional model is studied in which a particle moves in the field of two colliding zero-range potentials. Exact wave functions are constructed for the case of a head-on collision. The probability distribution of the ejected particle in momentum space is investigated. The numerical calculations are compared with the results of the adiabatic approximation.
