L X-ray production cross sections and their ratios in Ta, W and Pt for proton impact in the energy range 2–5.2 MeV

Abstract

L X-ray production cross sections and their ratios in Ta, W and Pt have been measured for the bombardment of protons in the energy range 2–5.2 MeV in steps of 0.4 MeV. The data in the energy range 3.8–5.2 MeV have not been reported so far. The X-ray production cross sections compare well (within 10%) with theoretical values obtained using the decay yield parameters of Krause and ECPSSR and Relativistic Plane Wave Born Approximation-with Binding energy and Coulomb deflection correction (RPWBA-BC) ionization cross sections. The derived relative X-ray intensity ratios are in good agreement with theory, within the combined uncertainties of theory and experiments. Comparison with previously published experimental results is also presented in this paper.
