An investigation of theL 2-L 3 Coster-Kronig transition probability for 63?Z?96

Measurement of Coster–Kronig yieldsf23for W, Pt, Pb and U

“…However, in the case of U, the present value is close to the semi-empirical value, that is the Z-region with abrupt discontinuity of f 23 . The present results show comparatively fair agreement with those from earlier radionuclide [21,22] and photo ionization measurements [8,19] for W, Pt and Pb, but are found to be higher than other experimental values [23][24][25][26][27][28][29] quoted in the present table. The other experimental values are, generally, from synchrotron and coincidence measurements.…”

“…Moreover, in the K x-ray energy region of ∼9-21 keV, the transmission through air column (1.5 cm) is constant (0.99) at two extreme energies and is only affected at the third decimal place. Thus, the ratios are determined as [21]; 0.156 ± 0.010 [22]; 0.119 0.116 0.123 0.105 ± 0.011 [23]; 0.1055 ± 0.011 [24]; 0.13 ± 0.002 [25]; 0.112 ± 0.002 [26,27]; 0.115 ± 0.004 [20]; 0.091 ± 0.010 [18] U 0.158 ± 0.019 0.147 ± 0.010 [28]; 0.146 ± 0.018 [23]; 0.140 0.167 0.139 0.140 ± 0.004 [20]; 0.139 [29] the equivalent Al target of the PE. ε b Kαβ and ε a Kβ are the efficiencies of the Si-PIN detector at the K b αβ and K a β energies of PEs and are determined from the given efficiency plots of the detector by the manufacturer [17].…”
