Özet

K-shell X-ray fluorescence cross-sections for some pure metals such as Cr, Fe, Co, Cu, Zn, Ga, Se, Y, Mo, Cd, In, Sn, Te, Ba, Ta, W and Bi have been theoretically and experimentally determined. The Cr, Fe, Co, Cu, Zn, Ga, Se, Y, Mo, Cd, In, Sn, Te and Ba metals were excited by 59.5 keV gamma-ray from 50 mCi Am-241 radioactive source and the Ta, W and Bi targets were excited by 123.6 keV gamma-ray from 25 mCi Co-57 radioactive source. The characteristic K X-rays emitted by samples were detected by using a super Si(Li) detector having a resolution of 150 eV at 5.9 keV. In addition, the I-K beta/I-K alpha intensity ratios for these metals were studied. The obtained experimental values of the K-shell X-ray fluorescence cross-sections and the I-K beta/I-K alpha intensity ratios have been compared with theoretical values. The measured values were in good agreement with theoretical values. (c) 2007 Elsevier B.V.. All rights reserved.
