Empirical M X-ray production cross sections for heavy elements by proton impact within Z-dependence analysis

Abstract

New empirical M-shell X-ray production cross sections have been deduced by introducing the dependence of the universal trend of the experimental data on the atomic number of the target, noted as "Z-dependence" for semiempirical cross sections in our previous work. For this effect, the updated experimental data (from 1980 to 2009) are used to calculate the empirical cross sections for heavy elements with 60 ≤ Z ≤ 90 by proton impact. Finally, a comparison is made between the deduced results and other earlier works.

Three dimensional (Z‐dependence), collective and individual semi‐empirical formulae for L X‐ray production and ionization cross section by protons impact within corrected ECPSSR theory and updated experimental data: a review

“…In our recent papers we have deduced a new semi‐empirical cross sections by introducing the dependence of the ratios (σ exp /σ ECPSSR ) on the atomic number of the target, noted as ‘Z‐dependence’ (pointing out that we are the first to propose this new treatment of the experimental data). With the same treatment, we generalize this formula for the L shell (L 1 , L 2 , L 3, L α , L β and L γ ).…”
