DOIAbstract
The X-ray absorption near-edge structure (XANES) at the PrLII,III thresholds was studied for tetravalent PrBaO3 and PrO2. The XANES spectra of both systems exhibit typical double-peaked “white-line” structures with substructures reflecting the different oxygen coordination in PrBaO3 and PrO2. These substructures are best visualized by the second derivative of the XANES spectra. We observe also characteristic differences between the respective LII- and LIII-edge spectra
