Abstract
X-ray absorption and resonant inelastic X-ray scattering measurements were performed on a single crystal of CeO2 near the Ce L-III edge at room temper ature and at 873 K. At 873 K the inelastic spectrum exhibits reversible cha nges, which are paralleled by reversible changes in the X-ray absorption sp ectrum. These changes are not due to chemical reduction of the sample, and may be indicative of evolution of the structure of oxygen sublattice in CeO 2 at elevated temperatures.
