Resonant photoemission experiments were performed in order to reveal the contributions of half-filled Gd 4f7 shell to the electronic structures of Sn0.95Gd0.05Te and Pb0.95Gd0.05S crystals. The influences of the Gd 4f6 final-state multiplet splitting and f-ligand hybridization on the shapes of the spectra are discussed.
