X-ray production in Ca, Sc, Ti, V, Cr, Mn and Fe by protons of 0.5-2 MeV energy

Abstract

Results from thin-target measurements of proton-induced K X-ray production cross sections for Ca, Sc, Ti, V, Cr, Mn and Fe (Z=20 to Z=26) in the incident energy range 0.5-2 MeV are reported and compared with other available results and with empirically fitted cross section data. Values of the K-shell ionisation cross sections are derived from the present results and are compared to the predictions of the BEA theory and to the PWBA theory corrected for Coulomb deflection, binding and relativistic effects. A simple empirical formula for the Z interpolation of cross section values at a given incident energy is presented.
