Abstract

Chemical effects on the L X-ray production cross-sections (, , , , and ) and L_i/L () X-ray intensity ratios for Hg, Pb, and Bi compounds were investigated. The samples were excited by 59.54 keV γ-rays from a ²⁴¹Am annular radioactive source. L X-rays emitted by samples were counted by a Si(Li) detector with resolution 157 eV at 5.9 keV. We observed chemical effect on the L X-ray production cross-sections and L_i/L X-ray intensity ratios for Hg, Pb and Bi compounds. The experimental values have been compared with the theoretically calculated values of pure elements.
