“…Using the relation (3), the value of f 23 was found to be 0.119 ± 0.003. The other measured values were 0.100 ± 0.009 [12], 0.101 ± 0.010 [13], 0.125 ± 0.013 [14]. Our measured value was lying above the values determined by synchrotron [12,13] but very close to the semi-empirical value of Krause [2] and slightly less than the relativistic value calculated by Chen et al [15].…”

“…The subshell-selective photoionization method based on energy-tunable monochromatic synchrotron radiation [9] offers the possiblity to measure all L-subshell CK yields. This method has been successfully applied to determine CK yields for solids [9][10][11][12][13] as well as for Xe [14].…”

The xenon L-subshell Coster-Kronig (CK) transition yields were revisited via high-resolution measurements of the Lα 1,2 (L 3 − M 4,5 ) and Lβ 1 (L 2 − M 4 ) x-ray emission lines. The L x-ray spectra were measured employing a Johansson-type curved crystal spectrometer and energy-tunable synchrotron radiation. The CK yields were derived from the relative L x-ray intensity jumps at the L edges by fitting the fluorescence intensities as a function of the photon energy to the L-subshell photoionization cross sections. The latter were obtained from the measured L-edge photoabsorption spectrum. Values of 0.118 ± 0.029, 0.383 ± 0.037, and 0.096 ± 0.016 were found for the f 23 , f 13 , and f 12 CK yields, respectively. Thanks to high resolution, the L 1 fluorescence yield of 0.059 ± 0.002 was also determined from intensity ratios of the well-resolved Lβ 4 (L 1 − M 2 ) and Lβ 1 (L 2 − M 4 ) lines.

“…In particular, for the Li-subshell uncertainties amount to about 20% which is due to Li-specific problems: experimentally, powerful coincidence techniques are not applicable here [6] and theoretically, the decay is governed by processes with small excess energy [7], where standard calculations [8] fail. Recently, a novel and universal technique for measuring yields of all subshells was introduced which makes use of the subshellselective photoionization with tunable synchroton radiation [9]. In an exploratory measurement this technique has provided stimulating results for Au {Z = 79) [9,10].…”
