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 f 12 = 0.201 ± 0.014, f 13 = 0.281 ± 0.027 and f 23 = 0.097 ± 0.016. These data represent valuable information for spectroscopists, considering the lack of data for L‐shell parameters.
