What is L-shell Coster–Kronig yields for Pb about?

## Abstract The __f__~13~ Coster–Kronig yield for Pb was determined as 0.60±0.03 using measured intensities of the Lα x‐rays emitted following selective ionization in the L~3~ sub‐shell by the Rb K x‐rays (__B__ < __E__~inc.~ < __B__) and of those emitted following ionization in the L~__i__~ (__i__ = 1, 2, 3) sub‐shells by 59.54 keV γ‐rays (__B__ < __E__~inc.~ < __B__~K~), __B__~K~ and __B__ being the K shell and L~__i__~ sub‐shell ionization thresholds of Pb, respectively. The measurements were performed using a ^241^Am annular source in direct excitation mode and in secondary excitation mode along with an RbNO~3~ secondary exciter as photon sources and an Si(Li) detector. Measurements of the __f__~12~ and __f__~23~ Coster–Kronig yields using similar experimental set‐ups are also discussed. It is concluded that the __f__~12~ and __f__~23~ Coster–Kronig yields for 12 elements with 59 ≤ __Z__ ≤ 90 measured by Oz __et al.__ using a similar experimental set‐up are not reliable.
