“…The detection of the induced x-ray fluorescence offers the possibility of extracting all subshell yields: the Coster-Kronig yields, the fluorescence yields and the Auger yield which are obtained from the normalization of all yields of a particular subshell to unity. Two variations of this method have been applied: the excitation of each subshell with one selected energy [18][19][20][21][22] and the excitation of the whole L range by an energy scan of the excitation beam [23][24][25][26][27][28]. The main advantage of this method is that all three Coster-Kronig yields are obtained simultaneously.…”

The method of selective photoionization of individual subshells by monochromatized synchrotron radiation has been employed to measure independently all Coster-Kronig and fluorescence yields of Er L subshells. Fitting the measured fluorescence intensities versus primary energy with the photoelectric cross sections derived the Coster-Kronig coefficients and fluorescence yields. The obtained yields were compared with tabulated data and a very good agreement among them was found.
