Figure 7
Normalized fluorescence Ni K-edge XANES spectrum of an iron sample alloyed with ∼1 at% of Ni (RPV steel). The spectrum is calibrated relative to the Ni K-edge at 8.333 keV. For comparison, the XANES K-edge spectra (measured in transmission) of Ni (f.c.c. structure) and Fe (b.c.c.) foils are shown. The inset shows the fluorescence spectra obtained from the alloy sample for two different excitation energies. The Ni XANES data were determined using the indicated region of interest (ROI).
