Comments
The resolution in the above table is the resolution given by the monochromator. The energy was calibrated by measuring the absorption edge of a reference: Co metallic foil (first maximum of the derivative set at 7709 eV). The resolution of the spectrometer analyser was 5.2 eV (FWHM of the elastic peak).
