Measurement of probabilities of radiative vacancytransfer from the L3 subshell to the M shell and the N shellfor Pb, Th and U

Abstract

The probabilities of radiative vacancy transfer from the L3subshell to the M shell and to the N shell are deduced for Pb, Thand U by measuring the L3 x-raysand using theoretical L3-subshell fluorescence yields. Toobtain L3 x-ray spectra of Pb, Th and U, the measurements aremade using selective photoionization of the L3 subshell inthese elements. The results are compared with theoretical valuesbased on the relativistic Dirac-Hartree-Slater calculations. Tothe best of our knowledge, these radiative vacancy-transferprobabilities are reported for the first time.
