Abstract

The X-ray absorption near-edge structure (XANES) at the PrL_II,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 L_II- and L_III-edge spectra.
