Comments

The resolution in the above table is the resolution given by the monochromator. The energy was calibrated by measuring the Br K edge of a KBr hydrated pellet (first maximum of the derivative set at 13474 eV).

Spatial parameters

Observation mode: single spot

Instrument #2

Instrument: X-ray Absorption Spectroscopy measured in transmission mode
Sample holder: Institut Néel autoclave, see Testemale et al., Rev. Sci. Instrum., 2005.
