DAFS THEORY

This section describes the resonant and non-resonant atomic scattering amplitudes, and shows how the atomic components combine to produce the observed smooth and oscillatory DAFS and XAFS signals from a crystal.

 
• Form of the Thomson and anomalous amplitudes
• Separation of the smooth and oscillatory DAFS terms
• Calculation of the EDAFS contributions using FEFF
• The DAFS kinematic unit cell structure factor
• The DAFS crystallographic weights
• The polarization dependence of the DAFS signals
