Alloying effect on K shell X-ray fluorescence parameters and radiative Auger ratios of Co and Zn in Zn xCo 1−x alloys

Abstract

In this study, σ Kα,β production cross-sections, ω K fluorescence yields, K β/K α, KLM/K α and KMM/K β intensity ratios of Co and Zn in different alloy compositions were measured. The alloying effects on the fluorescence parameters of Co and Zn were investigated. The changes in these parameters were interpreted according to the rearrangement of valance state electrons and the charge transfer process between the 3d elements which constitute the alloys. The samples were excited by 59.5 keV γ-rays from a 241Am annular radioactive source. K X-rays emitted by samples were counted by an Ultra-LEGe detector with a resolution of 150 eV at 5.9 keV.
