Measurement of Coster–Kronig vacancy transfer factor for L3 subshell X-rays of Au, Hg, Pb, Tl, Bi, Th and U at 59.5 keV

The Coster–Kronig vacancy transfer factors were measured for L3 subshell X-rays using the experimental Lα X-ray production cross section, the fraction of Lα X-rays, L3 subshell fluorescence yield and L3 shell photoionization cross section. The obtained experimental results were compared with the theoretical values. It showed that the agreement between the present experimental and theoretical results was very good.
