Total and differential cross sections for proton-induced K-shell ionization — Comparisons of experimental measurements with recent data and with theory

A theoretical investigation of ion-induced K-shell ionization based upon perturbed-stationary-state theory is presented. Results of calculations using this theory are compared with new data for both total and differential cross sections. Total cross sections were measured for 0.3 to 2.4 MeV protons in Ti, Cr, Co, Ni, Cu and Zn. Differential cross sections were measured for 2 MeV protons in Cu and Ni and 3 MeV 3 He ++ in Cu. Comparisons of our data for the total cross section with recent data obtained by other groups and with other theoretical results are given. The overall agreement generally is to within 10% and frequently is closer.
