“…The features a and c in the inset are well described by one-electron multiple scattering theory while the b feature is due to correlation effects. 16 The lack of resonances in the valence band is not surprising since the O 2p derived states have been shown to be bandlike with a bandwidth in the order of 4.5 eV. The data presented here are thus in agreement with the delocalized nature of the O 2p states.…”

Resonant photoelectron spectroscopy studies have been performed on the NiO valence band at photon energies corresponding to the Ni 2 p, 3p, and O 1s absorption thresholds. Strong resonances are seen in the vicinity of the Ni 2p threshold, which confirm earlier conclusions from the weaker resonances seen at the Ni 3p threshold. No valence-band resonance is observed at the O 1s threshold. The analysis of this data confirms the picture of NiO as a strongly correlated charge-transfer insulator by identifying the highest-lying states as being of mainly 3d 8 L គ final-state character. The existence of localized excited Ni states, as well as the delocalized nature of the O states, are confirmed. Comparisons with the configuration-interaction model and quasiparticle calculations are also made.

“…Several Ο K-edge features are observed in both spectra, including a fairly sharp feature at 533 eV and a relatively strong feature at 541 eV. The peak positions of these two features are very similar to those reported previously for thick nickel oxide (NiO) using either electron energy loss spectroscopy 43 · 44 or near-edge X-ray absorption spectroscopy by means of measuring the low-energy electron yield 45 .…”

“…The third region including peaks (c) and (d) can be interpreted in terms of the multiple scattering of the excited electron with low kinetic energy. These features are sensitive to the local structure around the oxygen site, which means that the features are similar if crystal structures are identical [388]. More precisely, the peaks (c) and (d) arise from multiple scattering within oxygen shells of increased size around the excited atom [389] and their peak positions can be correlated to the interatomic distances between oxygen atoms through the resonance condition [390].…”
