Min - Max () Sampling () Resolution () Position accuracy () Absorption edge #1 7100.0 - 7880.0 0.371 (L3: 7.2428 ) - 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: Cu metallic foil (first maximum of the derivative set at 8979 eV).
Definition: incidence and emergence angles are positive with origin at nadir. Emergence angle in transmission is larger than 90° (=180°-i).
