Fluorescence and Coster - Kronig Yields ofLSubshells in Hg from the Decay ofAu198andTl204

Abstract
Coincidences between L x rays and Kα x rays, emitted during the filling of K and L vacancies in Hg in the decay of Au198 and Tl204, are measured with high-resolution Si(Li) and Ge(Li) x-ray spectrometers in a fast-coincidence arrangement. The following L-subshell fluorescence and Coster-Kronig yields are measured: ω2=0.316±0.010, ω3=0.300±0.010, and f23=0.190±0.010.
