Chemical Effects on K-beta/K-beta X-Ray Ratios in Coordination-Compounds of Some 3d Elements
(Iop Publishing Ltd, 1993) KUCUKONDER, A; Şahin, Y; Büyükkasap, E; Kopya, A
The effects of changes in coordination number on Kbeta/Kalpha x-ray intensity ratio have been studied experimentally. The Kbeta/Kalpha x-ray intensity ratios for both pure Cr, Mn and Cu and their various chemical compounds with tetrahedral and octahedral symmetry are investigated using a Ge(Li) detector. The measured results indicate that the Kbeta/Kalpha ratios for compounds with tetrahedral symmetry are in general larger than those with octahedral symmetry. The obtained Kbeta/Kalpha x-ray intensity ratios are comparable with both previous published experimental and theoretical results.
Chemical Effects on the Kβ/Kα Intensity Ratios in First-Row Transition Element Compounds
(Polish Acad Sciences inst Physics, 1999) Küçükönder, A; Büyükkasap, E; Yilmaz, R; Sahin, Y
Chemical effects on the K-beta/K-alpha, X-ray intensity ratios for some first-row transition element compounds were studied experimentally and calculated. The vacancies in the K shell were created by 59.5 keV gamma rays from an Am-241 radioactive source and characteristic X-ray radiation from sample was measured by using Si(Li) and Ge(Li) detectors. The calculations were carried out using Brunner's model. The calculated relative K-beta/K-alpha X-ray intensity ratios are in good agreement with the present and the previously published experimental data.
The Effect of The Chemical Environment on The K-beta/K-alpha X-Ray Ratio
(Editrice Compositori Bologna, 1993) KUCUKONDER, A; Şahin, Y; Büyükkasap, E
Chemical effects on the Kbeta/Kalpha X-ray intensity ratios were investigated for different constitutions of Ti, V, Fe, Se, Br, Zr and Ce by a Ge(Li) X-ray detector. The vacancies were produced by heavily filtered Am-241 gamma-rays. It is found that the Kbeta/Kalpha X-ray intensity ratios measured with compounds deviated up to 12% from the corresponding values of the pure elements (Ti, V, Fe) are larger than for the others (Se, Br, Zr and Ce).
