Chemical Effects on L Shell Cross-Sections and Fluorescence Yields of Th and U Compounds

Chemical effects of some Th and U compounds on average L shell fluorescence yields (ϖL) and cross-section (σLℓ, σLα, σLβ, σLγ) were investigated. The samples were excited by 59.5 keV photons from an 241Am source. L x-rays from samples were measured using a Si(Li) detector with resolution 155 eV at 5.9 keV. We observed chemical effects on the average L shell fluorescence yield (ϖL) for Th and U compounds. Experimental values were compared with calculated theoretical values of pure U and Th elements.
