WebOct 20, 2016 · To model the first shell EXAFS of FeO, a simulation of the EXAFS for the Fe–O scattering path is calculated by FEFF from a cluster derived from the known crystal parameters for FeO. Setting S 2 0 to 0.75, values for N, R, σ 2, and E 0 are refined until the model for χ best matches the complex χ(R) of the measured data. The results of this ...
