Mo L-shell x-ray production cross section by heavy Ar¹¹⁺ ions near the Bohr velocity

Mo L-shell x rays have been measured for the bombardment of highly charged heavy Ar¹¹⁺ ions in the energy range of 1 MeV − 3 MeV. The new experimental data for individual L-subshell and total L-shell x-ray production cross sections were obtained and compared with the theoretical calculations of BEA, PWBA, ECPSSR, ECUSAR, and that of BEA modified by the Coulomb repulsion (CR) and effective nuclear charge (Z_eff). The effect of multiple ionization in the atomic parameters was considered. The smaller the fluorescence yield of single ionization, the greater the enhancement of x-ray radiation caused by multiple ionization. On the whole, the BEA-Z_eff-CR-MI simulations adopting appropriate multiple ionization atomic parameters are found to be in good agreement with the data.
