WebGenerally, the metal K-edge X-ray absorption spectrum is divided into two regimes: X-ray absorption near-edge structure (XANES) and extended X-ray absorption fine structure (EXAFS). The range up to 50–1000 eV above the absorption edge is the EXAFS regime, which is a single-scattering-dominated region.
