The resonant scattering factor for an atom is [5]
is the portion of due solely to the resonant electron of the resonant atom and is modulated by the same complex whose imaginary part is measured in XAFS.
The diffraction intensity
is measured across the resonant energies of the material. The atomic anomalous scattering terms, and introduce rapid variation in the diffracted intensity in the energy region around the resonant energy. The term introduces oscillatory structure to the DAFS above the resonant energy. These oscillations contain local structural information similar to that in XAFS.
