The valence-band photoemission of the (010) surfaces of CeNi single crystals has been observed. The features occurring in angle-resolved normal-emission spectra do not show an appreciable amount of dispersion. The energy distribution curves are squeezed and narrower than those suggested by an existing energy-band calculation. Resonant photoemission has been observed both near the 3p core electron excitation threshold of Ni and the 4d threshold of Ce. An aspect of the super-Coster-Kronig final state with a post-collision interaction is found near the onset of the resonance in the two-hole bound-state satellite
