Measurement Of L-subshell X-ray Production Cross Section Of Lead By Fluorine Ions Bombardment

Production cross-section of Pb L-shell X-ray induced by 20-50 Mev F5+ion was measured in this work, The relationship of X-ray production cross-section and impact ion energy was represented. At the same time, inner-shell ionization cross-section given by plane-wave Born approximation (PWBA) theory and the ECPSSR theory was transformed to L-subshell X-ray production cross-section by using Radiative transition probability, Coster-Kroning transition probability and fluorescence yield.The results were compared with the experimental results, It was found that reasonable agreement between theory and experiment is observed, the ECPSSR theory is closer to the experiment.At the same time, Production cross-section of Pb L-shell X-ray induced by 30-80 Mev F6+ion was compared with that of F5+ion incidence, The rusults showed:In the same incidence energy,the higher the incedent ion charge state, the bigger the L-subshell X-ray prodection cross-section.
