Valence-band photoemission studies, using synchrotron light and employing Fano resonances to enhance f-derived features, were made of the three known heavy-fermion superconductors: CeCu/sub 2/Si/sub 2/, UBe/sub 13/, and UPt/sub 3/. The results for CeCu/sub 2/Si/sub 2/ and UBe/sub 13/ contrast markedly with those reported earlier, reflecting closer control of surface contamination in the present study. We infer from the present study and other considerations that in all three systems there is sig- nificant hybridization between the f electrons and the nearest-neighbor ligands, which may be essential to the phenomenon of heavy-fermion superconductivity.
