Abstract:

The requirements for a reliable analysis program of XAFS spectrum to obtain structural information are listed. Besides the more generally recognized items, it is emphasized that criteria to assess whether the model found is reasonable, and a fast and reliable error analysis which assures that the information content of the data is not exceeded, should be included. The University of Washington analysis program UWXAFS is described which satisfies the listed requirements and includes multiple scattering (MS) contributions in an efficient manner utilizing the FEFF program, and fits in R-space to allow limiting the MS paths.
