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: W metallic foil (first maximum of the derivative set at 12607.0 eV).
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.
