Chemical effects on L$_\alpha$, L$_\beta$, L$_\gamma$, L$_{\mathsf l}$, and L$_\eta$ X-ray production cross-sections and L$_{\mathsf i}$/L$_\alpha$ X-ray intensity ratios of Hg, Pb and Bi compounds at 59.54 keV

Abstract.

Chemical effects on the L X-ray production cross-sections ($\sigma_{L_{\alpha}}$, $\sigma_{L_{\beta}}$, $\sigma_{L_{\gamma}}$, $\sigma_{L_{l}}$, and $\sigma_{L_{\eta}}$) and L _i /L$_{\alpha}$ ($i = \alpha, \beta, l, \eta$) X-ray intensity ratios for Hg, Pb, and Bi compounds were investigated. The samples were excited by 59.54 keV $\gamma$-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$_{\alpha}$ X-ray intensity ratios for Hg, Pb and Bi compounds. The experimental values have been compared with the theoretically calculated values of pure elements.
