Proton-induced X-ray production in titanium, nickel, copper, molybdenum and silver

Abstract

Measurements have been made of the K X-ray production from elements bombarded with protons. Thick targets of Ti, Cu, Ni, Mo and Ag have been used and the yield of X-rays measured as a function of proton energy in the range 1-3 MeV. From these measurements values of the K-shell ionization cross sections in this energy range have been calculated and these have been compared with the results of other workers and with the predictions of the plane wave Born approximation (PWBA) and the binary encounter approximation (BEA).
