英文摘要	L subshell X-rays of Cd-48 and In-49 have been measured for the impact of protons with energies from 75 to 250 keV. Obviously, it is found that L gamma(2) (abbreviation L gamma(2,3) for Cd-48 and L gamma(2,3,4) for In-49) X-ray emission is enhanced in comparison with L gamma(1) X-ray emission. The relative intensity ratios of L gamma(2) to L gamma(1) X-ray are larger than the atomic data and increase with decreasing proton energy. This is caused by the multiple ionization of outer-shell electrons. To verify this explanation, the enhancements for relative intensity ratio of L iota and L beta(2) to L alpha X-ray in experiments are discussed, and the direct ionization cross sections of 4d, 5s, and 5p electrons are calculated using BEA theory.
