Prompt gamma-ray yields from proton bombardment of transition elements (Ti to Zn)

Abstract

Gamma-ray yields from bombardment with protons of thick targets of Ti, V, Mn, Cr, Fe, Co, Ni, Cu and Zn are tabulated for proton energies ranging between 0.6 and 3.2 MeV. The applications of these reactions for quantitative analysis of these chemical elements are discussed. The sensitivity of this technique of analysis is poorer than the PIXE method for these transition elements, but is sufficient for rapid and accurate quantitative analysis of alloys when elements are present in concentrations down to 1%. The knowledge of the γ-ray energies and intensities produced by the bombardment of these elements with protons is also necessary for solving interferences with several γ-rays induced in light elements, for which the proton induced γ-ray technique is sensitive, without any correction for photon attenuation.
