New Regularization Method for EXAFS Analysis
- Conference date: 9-14 July 2006
- Location: Stanford, California (USA)
As an alternative to the analysis of EXAFS spectra by conventional shell fitting, the Tikhonov regularization method has been proposed. An improved algorithm that utilizes a priori information about the sample has been developed and applied to the analysis of U L3‐edge spectra of soddyite, (UO2)2SiO4⋅2H2O, and of U(VI) sorbed onto kaolinite. The partial radial distribution functions g1 (UU), g2 (USi), and g3 (UO) of soddyite agree with crystallographic values and previous EXAFS results.
