(a) Normalized Ni K-edge (8333 eV) XAS spectra measured in the fluorescence of NiO samples with decreasing sample mass pressed into 13 mm pellets. The absorption-edge step from each sample was measured from the transmission geometry data. (b) Comparison of the normalized XAS spectra obtained in 1 s for the 0.120 edge-step NiO pellet obtained in transmission and fluorescence modes. |
