L i (i=1-3) subshell fluorescence and Coster-Kronig yields for elements with 70≤Z≤92

The atomic inner-shell vacancy decay processes comprised of radiative and nonradiative transitions are characterized by the fluorescence, Auger and Coster-Kronig yields. We present a review of our recent measurements of the L i (i=1, 2, 3) sub-shell fluorescence yields (ωi ) and the L1-L3 Coster-Kronig transition probabilities (f 13) for elements with 70≤Z≤92 following photoionization. The comparison of the measured ωi and f 13 values with the theoretical ones, based on the relativistic Dirac-Hartree-Slater (RDHS) model calculations, indicated the need for more refined calculations of transition probabilities for different Coster-Kronig transitions
