Coster-Kronig yields in silver measured with synchrotron radiation
The Coster-Kronig transition probabilities /ital f//sub /ital ij// for shifting avacancy from the /ital L//sub /ital i// to the /ital L//sub /ital j// subshell of Ag have beenmeasured by differential photoionization of the subshells with synchrotronradiation by observing the intensity of the ensuing/ital L//sub /ital j//-/ital M//sub 4,5/M/sub 4,5/ Augertransitions. In the course of the analysis, spectator satellites in these Augerspectra were identified. The following Ag Coster-Kronig yields were determined:/ital f//sub 23/=0.16+-0.03,/ital f//sub 12/=0.044+-0.004, and/ital f//sub 13/=0.61+-0.05. While /ital f//sub 23/agrees very well with relativistic independent-particle calculations by Chen/ital et/ /ital al/. (Phys. Rev. A 24, 117 (1981)), /ital f//sub 12/and /ital f//sub 13/ fall below predictions by 35% and 18%, respectively, inqualitative accord with expected many-body effects.
