The synchrotron photoionization method was applied to measure L-subshell Coster-Kronig yields for Tb. This method is based on the capability of tuning the energy of the synchrotron photons producing a selective subshell ionization. A foil sample of Tb was irradiated and characteristic spectra were recorded. Data were analysed using a new formalism (based on a matrix representation) to express x-ray fluorescence intensities involving Coster-Kronig transitions. The results obtained were f12 = 0.201 ± 0.014, f13 = 0.281 ± 0.027 and f23 = 0.097 ± 0.016. These data represent valuable information for spectroscopists, considering the lack of data for L-shell parameters.
