FOURIER-ANALYSIS OF EXAFS AND XANES DATA - A SELF-CONTAINED FORTRAN PROGRAM-PACKAGE - THE 3RD VERSION

A third version of Fourier analysis of XANES and EXAFS data, a self-contained FORTRAN program-package, is described. By the direct dialog between the user and the indirect command processor, based on XANES and EXAFS spectra, there is the possibility to obtain the electronic and structural parameters. An improved smoothed procedure is used to extract more informations from XANES spectra by second derivative analysis. The true energy position of maxima and the full width at half maximum (FWHM) can be determined. The XANES spectrum and the first and second derivative are determined by cubic spline functions, the phase-shift function and numerical values of structural parameters for the Ni foil spectrum are given. © 1990.
