Correlation satellite lines originating from the strong mixing between 5s¹5p⁵, 5s²5p³nd (n=5, 6, 7, ...) and 5s²5p³ms (m=6, 7, 8, ...) configurations in the final state of the N_4,5-O₁O_2,3 Auger decay of Xe and between 4s¹4p⁵, 4s²4p³nd (n=4, 5, 6, ...) and 4s²4p³ms (m=5, 6, 7, ...) final-state configurations in the M_4,5-N₁N_2,3 Auger decay of Kr have been studied by means of synchrotron-radiation excited electron spectroscopy and relativistic multiconfigurational Dirac-Fock calculations. Improvements in experimental and computational methods have made it possible, for the first time, to resolve and to assign most of the satellite lines with high accuracy.
