| Summary: In this study, K and L X-ray production cross sections, fluorescence yields, intensity ratios and vacancy transfer probabilities were measured for the element and their compounds in the atomic range 73?Z?79. 123.6 keV and 59.543 keV gamma photons emitted by an annular 25 mCi 57-Co and 50 mCi 241-Am radioactive sources were used to excite the K and L shells of the sample, respectively. The K and L X-ray emitted from the samples were counted by an Ultra-LEGe detector with a resolution of 150 eV at 5.9 keV.The obtained values were compared with theoretically calculated values and the other theoretic, semi-empirical and empirical values in the literature. The differences between these values were explained according to chemical effect and multiply ionization effect.
