XAFS Data Analysis Using FEFF

The FEFFIT home page

FEFFIT is a computer program for the analysis of XAFS data. It is designed to fit experimental XAFS spectra to theoretical calculations from FEFF. FEFFIT is fairly easy to use. Fitting can be done in k or R space, and error analysis is automatically done, and a wide-range of options are given for modelling XAFS data. Follow this link to the FEFFIT home page.

LASE software analyzes XAS data and includes an interface with FEFF, both to create the feff.inp file from structural data and to create a fitting model (in k-space) from the set of feffxxxx.dat file. Follow this link to the LASE home page.
MAX (Multiplatform Applications for XAFS) is a new EXAFS data analysis package inspired by and replacing the old "EXAFS pour le Mac". The main difference is that it is no more "pour le Mac" but Multi-platform : MacOSX (Universal), Windows (XP, Vista, and 7), Linux. MAX includes all the EXAFS data analysis functions from reading raw data files to fitting single and mulitple scattering paths models. NEW : XANES normalization, FEFF mutiple scattering paths analysis, self absorption corrections in XANES and EXAFS,...and more.

If we have left your analysis package off the list, please send mail to Prof. J.J. Rehr.

The European Synchrotron Radiation Facility keeps an archive of freely available XAFS analysis software along with other information about XAFS theory and analysis code (including Feff and all the packages mentioned above).
