The xenon L-subshell Coster-Kronig (CK) transition yields were revisited via high-resolution measurements of the Lalpha{sub 1,2} (L{sub 3}-M{sub 4,5}) and Lbeta{sub 1} (L{sub 2}-M{sub 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{sub 23}, f{sub 13}, and f{sub 12} CK yields, respectively. Thanks to high resolution, the L{sub 1} fluorescence yield of 0.059+-0.002 was also determined from intensity ratios of the well-resolved Lbeta{sub 4} (L{sub 1}-M{sub 2}) and Lbeta{sub 1} (L{sub 2}-M{sub 4}) lines.
