Abstract
We present an EXAFS-oriented theory program based on the popular Feff8 and providing an application programming interface designed to make it easy to integrate high-quality theory into EXAFS analysis software. We then use this new code to examine the impact of self-consistent scattering potentials on EXAFS data analysis by methodical testing of theoretical fitting standards against a curated suite of measured EXAFS data. For each data set, we compare the results of a fit using a well-characterized structural model and theoretical fitting standards computed both with and without self-consistent potentials. We demonstrate that the use of self- consistent potentials has scant impact on the results of the EXAFS analysis.Citation
