Determination of some fluorescence parameters of L sub-shells for Th and U at 59.54 keV photon energy
MetadataShow full item record
The L X-ray fluorescence cross-sections at 59.54 keV, L sub-shell fluorescence and Auger yields, L sub-shell level widths, life times and some selected radiative transfer probabilities of L to M, N and O sub-shells were determined using Energy Dispersive X-ray Fluorescence for Th and U. The experiments were performed with a Si(Li) detector and an Am-241 radioactive annular source in excitation geometry. The results are in good agreement with other comparable values within experimental uncertainties.
