Abstract

Partial L X-ray production cross sections for low-energy proton bombardments have been calculated in the relativistic plane-wave Born approximation, including the corrections for the Coulomb-deflection and binding-energy effects. The results obtained are compared graphically with the experimental values for Lα, Lβ, Lγ and Ll X-ray production cross sections. The experimental data for various target elements are expressed as a ratio to the theoretical value and plotted against an average reduced velocity parameter. This plot shows an approximately universal behaviour for different target elements and for different partial X-ray production cross sections. The agreement between theory and experiment is in general not so good in the low-energy region. The reasons for better agreement in the case of relative X-ray intensity ratios and correlation between subshell ionization cross sections and partial X-ray production cross sections are discussed.
