摘要：

K-shell ionization of thick targets of Ti, Fe, Ni, and Zn by 60-150-keV protons has been investigated. Experimental x-ray production cross sections have been determined as a function of proton energy. Absolute ionization cross sections are compared to predictions of the perturbed-stationary-state theory, including Coulomb deflection and approximate relativistic corrections (CPSSR). It is found that the CPSSR systematically overpredicts the values for the experimental data at the lower proton energies. © 1979 The American Physical Society.
