Abstract

The L-shell X-ray production cross sections for Ag, In and Sn by positron impact have been calculated with two methods based on classical mechanics, i.e. the binary-encounter approximation and the classical trajectory Monte Carlo method. The results are compared with the experimental data and quantum mechanical calculations. We found that both classical treatments describe the inner-shell ionization processes by positron impact reasonably well.
