L-shell x-ray production cross sections of Pd, Ag, and Sn for incident proton energies in the range 3--12 MeV and oxygen ions in the range 15--40 MeV

Absolute L-shell x-ray production cross sections have been measured for thin targets of Pd, Ag, and Sn at 1-MeV increments for incident protons in the range from 3 to 12 MeV and in 5-MeV increments for oxygen ions in the range from 15 to 40 MeV. L-shell ionization cross sections are calculated from theoretical average L-shell fluorescence yields and then compared to both plane-wave Born-approximation (PWBA) and binary-encounter-approximation (BEA) theories. The data are found to be higher than the theoretical predictions except at the lowest projectile energies
