FEFF analysis of the isolated EDAFS oscillations

Once the fine structure has been isolated and normalized with one of the methods described above, it can be analyzed to obtain local structural information. The analysis proceeds in a manner that is almost identical to modern MS-XAFS analysis : A model of the structure is constructed, and FEFF is used to calculate the amplitude, phase and degeneracy of each photoelectron scattering path. The model is fit to the DAFS data to obtain the desired XAFS-like structural and spectroscopic information [4, 23].
