L-subshell X-ray intensity ratio of Xenon for 6 MeV Xe20+ impact on selected targets

The L-shell X-ray emission of Xenon was measured for 6 MeV Xe20+ ions impacting on V, Fe, Ni, Cu and Zn targets. The distinct L-subshell X-rays and the energy shift were observed. The L-shell ionization and the multiple ionization of the outer-shell were investigated. In addition, the relative intensity ratios of Lα1,2 to Lβ1,3,4 and Lβ2,15 were obtained, which approximately decrease linearly with the increasing target atomic number. That was interpreted by considering multiple ionization of the outer-shell electron.
