On the semiclassical impulse approximation for electron capture in asymmetric ion-atom collisions

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

A derivation of the impulse approximation for the capture of a targetK-shell electron by a light projectile in ion-atom collisions is given in the framework of the semiclassical approximation. The impact-parameter dependence of the capture probability is calculated numerically without further approximations, and shows good agreement with recent experimental results for protons colliding with Ne and Ar. The validity of several peaking approximations and the relation to ionisation theories is briefly discussed.
