K (beta) to K (alpha) X-ray intensity ratios and K to L shell vacancy transfer probabilities of Co, Ni, Cu, and Zn

Abstract

The K to L shell total vacancy transfer probabilities of low Z elements Co, Ni, Cu, and Zn are estimated by measuring the K (beta) to K (alpha) intensity ratio adopting the 2 pi-geometry. The target elements were excited by 32.86 keV barium K-shell X-rays from a weak Cs-137 gamma-ray source. The emitted K-shell X-rays were detected using a low energy HPGe X-ray detector coupled to a 16 k MCA. The measured intensity ratios and the total vacancy transfer probabilities are compared with theoretical results and others' work, establishing a good agreement.
