K and L- shell X-ray Transition-Probability Ratios by Proton Bombardment

Abstract

The present work aimed to study the energy dependence of K α /K β X-ray transition-probability ratios for the elements Fe, Cu, Se, Ag and L α /L β , L α /L γ and L α /L ι X-ray transition-probability ratios for the elements Ag, Pb and Bi. It has been measured by proton bombardment in the energy range of 1.5 to 3.0 MeV. Our results provide constant transitionprobability ratios for K shell X-ray with varying proton energies, while for L X-ray, transition probability ratios show variation with incident proton energy. X-ray transition probability has been compared with the theoretical ratios, calculated by relativistic Hartee-Slater theory and using sub-shell direct ionization cross-sections. .
