Abstract :
The present work aimed to study the energy dependence of Kα/Kβ X-ray transition-probability ratios for the elements Fe, Cu, Se, Ag and Lα/Lβ, Lα/Lγ and Lα/Lι 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 transition- probability 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.
