Figure 6
Time-resolved X-ray absorption near-edge spectra (XANES) measured at P64 during the exposure of an Nb thin foil (8 µm thickness) to an air-atmosphere of 10−3 mbar at 900°C. The displayed spectra were recorded with 0.5 s per scan (1 Hz), and one spectrum is displayed every three minutes (colour code from dark blue to dark green with increasing time). In the inset, the shift of the absorption edge defined as the first inflection point of the spectrum is shown.
