Chemical effect on the K and L shell intensity ratios of Hf compounds

Chemical effects on the Ki/Kj (i=α2, β, β1, β2; j=α, α1, β1), Li/Lα (i=l, β, γ) and Li/Kj (i=l,α, β, γ; j=α1, α2) x-ray intensity ratios for (Hf) compounds were investigated. The samples were excited by 123.6 keV γ-rays from a 57Co annular radioactive source. K and L x-rays emitted by samples were counted by an Ultra-LEGe detector with a resolution of 150 eV at 5.9 keV. We observed a chemical effect on the Li/La and Li/Kj x-ray intensity ratios for Hf compounds. However, for the Ki/Kj intensity ratios, dependence on the chemical state of Hf compounds is almost negligible. The experimental values have been compared with the theoretically calculated values of pure Hf
