AverageL-shell fluorescence, Auger, and electron yields

The dependence of the average $L$-shell fluorescence and Auger yields on the initial vacancy distribution is shown to be small. By contrast, the average electron yield pertaining to both Auger and Coster-Kronig transitions is shown to display a strong dependence. Numerical examples are given on the basis of Krause's evaluation of subshell radiative and radiationless yields. Average yields are calculated for widely differing vacancy distributions and are intercompared graphically for $40\le Z\le 100$ in the case of the fluorescence and Auger yields, and $12\le Z\le 100$ in the case of the electron yield. Average fluorescence and Auger yields are found to differ by less than 7% from the respective $L_3$ subshell yields in most cases of inner-shell ionization.
