The photon-energy (h1/2) dependence of the angle-integrated and angle-resolved photoemission from Ni(110) has been measured to investigate the valence-band satellite. Contrary to the earlier observations, we found that the satellite moves with h1/2. The satellite centroid is observed at 1/46.0 eV below the Fermi energy (EF), away from the 3p-3d resonance, and at 1/46.8 eV in the region of the resonance. The difference spectra show that on resonance the highest-binding-energy part (at 1/47.3 eV) of the satellite is additionally enhanced. The results are discussed in terms of the singlet and triplet satellites.
