Abstract:

As an alternative to the analysis of EXAFS spectra by conventional shell fitting, the Tikhonov regularization method has been proposed {[}1]. An improved algorithm that utilizes a priori information about the sample has been developed and applied to the analysis of U L-3-edge spectra of soddyite, (UO2)(2)SiO4 center dot 2H(2)O, and of U(VI) sorbed onto kaolinite. The partial radial distribution functions g(1)(UU), g(2)(USi), and g(3)(UO) of soddyite agree with crystallographic values and previous EXAFS results.
