Min - Max ($eV$) Sampling ($eV$) Resolution ($eV$) Position accuracy ($eV$) Absorption edge #1 11447.5 - 12414.3 0.593 $Pt$ (L3: 11.5637 $keV$) - 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: Pt metallic foil (first maximum of the derivative set at 11564 eV).
Definition: incidence and emergence angles are positive with origin at nadir. Emergence angle in transmission is larger than 90° (=180°-i).
