Li (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 Li (i=1, 2, 3) sub-shell fluorescence yields (ωi) and the L1–L3 Coster-Kronig transition probabilities (f13) for elements with 70⩽Z⩽92 following photoionization. The comparison of the measured ωi and f13 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.
