Electronic Relativistic Effect in Inner-Shell Ionization Cross Section and Electron Momentum Distribution

Research output: Contribution to journalArticle

Abstract

The inner-shell ionization cross section by charged-particle impact is expressed in the form of the momentum distribution of the target electron. Based on this approximation, the correction factor for the electronic relativistic effect is obtained as the ratio of the relativistic to nonrelativistic momentum distribution at the momentum corresponding to the minimum momentum transfer in the ionization process. It is found that for K-, Lx- and L3-shell ionization cross sections the correction factor obtained from the momentum distribution is in good agreement with the exact relativistic calculation.
