Özet

We have measured sigma(Lc), sigma(Lx1.2),sigma(L eta), sigma(L beta), sigma(L71), sigma(L gamma 23.68B), sigma(L gamma 4.4'),L-gamma 5, sigma(L gamma TOTAL) XRF cross-sections with a Si (Li) detector for some elements in the atomic range 72 <= Z <= 92. The samples were excited 59.537 keV photons emitted from an 24 Am radioisotope source with 100 mCi activity. These cross-sections also have been calculated theoretically by using atomic parameters. Relative intensity ratios of L X-rays have determined by using these cross-sections both experimentally and theoretically. Our experimental relative intensity ratios of L X-rays have compared the experimental values available in the literature. (c) 2005 Elsevier B.V. All rights reserved.
