ATHENA, ARTEMIS, HEPHAESTUS: data analysis for X-ray absorption spectroscopy using IFEFFIT.
Bruce Ravel,Matthew Newville +1 more
TL;DR: A software package for the analysis of X-ray absorption spectroscopy (XAS) data is presented, based on the IFEFFIT library of numerical and XAS algorithms and is written in the Perl programming language using the Perl/Tk graphics toolkit.
Journal ArticleDOI
Real-space multiple-scattering calculation and interpretation of x-ray-absorption near-edge structure
TL;DR: In this paper, a selfconsistent real-space multiple-scattering (RSMS) approach for calculations of x-ray-absorption near-edge structure (XANES) is presented and implemented in an ab initio code applicable to arbitrary aperiodic or periodic systems.
Journal ArticleDOI
The UWXAFS analysis package : philosophy and details
TL;DR: The University of Washington analysis program UWXAFS is described which satisfies the listed requirements and includes multiple scattering contributions in an efficient manner utilizing the FEFF program, and fits in R-space to allow limiting the MS paths.
Journal ArticleDOI
Analysis of multiple-scattering XAFS data using theoretical standards
TL;DR: Theoretical standards for scattering amplitudes and phase shifts are often necessary for XAFS analysis, as for cases in which multiple scattering paths are important over the R-range of interest.
Journal ArticleDOI
ATOMS: crystallography for the X‐ray absorption spectroscopist
TL;DR: The main use of the ATOMS program is to generate input data for the ab initio, multiple scattering, x-ray absorption spectroscopy code FEFF, but the code offers many additional features, including useful calculations involving absorption coefficients and simulations of Diffraction Anomalous Fine-Structure (DAFS) spectra.
