Spectroscopic Evidence for Localized and Extendedf-Symmetry States in CeO2
Open accessAbstract
The occupied and empty electronic states of the insulator Ce${\mathrm{O}}_{2}$ have been studied by high-energy spectroscopies. The outer-level spectra reveal empty localized $4{f}^{1}$ states within the band gap. The core-level spectra display different final-state populations of the $4f$ localized states which are well predicted by a many-body calculation taking into account the presence of $f$-symmetry admixture in the valence band. A mixed valence can be definitely excluded in Ce${\mathrm{O}}_{2}$.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
