Proton Induced L-Subshell Ionization on Silver and Iodine

L-x-ray production cross sections were measured in the proton energy range 0.3-5.0 MeV for Ag and I. Sub shell ionization cross sections were extracted and compared with predictions of the perturbed stationary state theory, the binary encounter approximation and the semiclassical approximation with binding, polarization, relativistic, energy loss and Coulomb deflection corrections included (ECPSSR, BEABC, SCABCR). The agreement is quite good especially for the shape and the magnitude of the kink in the L1 subshell cross section due to the node of the 2s wavefunction.
