Ca K-edge X-ray absorption near-edge structure spectra.

(a) Experimental and theoretical spectra of CaTiO3. (b) Experimental spectra of Ba1−xCaxTi2O5. (c) Theoretical spectra of Ba1−xCaxTi2O5 with Ca at the Ba1 (4c) site and the Ba2 (2b) site. The theoretical spectra are shifted by ΔE = −13.4 eV (ΔE/E = −0.33%) for aligning the peak energy of the experimental spectra with that of the theoretical spectra.
