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: Se metallic foil (mesh) (first maximum of the derivative set at 12658 eV). The resolution of the spectrometer analyser was 3.1 eV (FWHM of the elastic peak).
Observation geometry
directional
Observation mode
fixed angles
Comments
Emitted x-rays are collected in a solid angle directed at 90 degrees from the incident beam.
