The L-3 subshell x-ray intensity ratios for Hg, Bi, Th, and LT have been measured using an annular source double reflection geometrical setup. Only the L-3 subshell of these elements were excited by the K x rays of the elements used as the primary targets. A Si(Li) detector connected to a Nuclear Data 66 B multichannel analyzer was used for counting. Tbe experimental values were compared with theoretical values calculated using emission rates based on the Dirac-Hartree-Slater model and Dirac-Fock model.
