Measurement of L-Shell X-ray Production Cross Section of Pb by Fluorine Ion Bombardment

Production cross section of Pb L-shell X-ray induced by 2050 MeV F⁵⁺ ion was measured, and the relationship of X-ray production cross section and impact ion energy was represented. At the same time, inner-shell ionization cross sections given by plane-wave Born approximation (PWBA) theory and the ECPSSR theory were transformed to L-subshell X-ray production cross section by using radiative transition probability, Coster-Kronig transition probability and fluorescence yield. The results were compared with the experimental results. It shows that reasonable agreement between theory and experiment is observed, and the ECPSSR theory is closer to the experiment.
