XAFS can be interpreted as due to scattering of the photo-electron ejected from the absorbing atom by the photo-electric effect. XAFS is commonly divided into the ‘near edge’ region (XANES or NEXAFS) and the ‘extended’ region (EXAFS) Mainly single scattering contributions Multiple scattering contributions

EXAFS is an interference effect that depends on the wave nature of the photoelectron. It is therefore convenient to think of EXAFS in terms of the photoelectron wavenumber, k, rather than x-ray energy ( ) 8. 0 2. E E h m k = e − π. m. e: mass of electron.

The extraction of EXAFS-part, χ(k). Three methods for the construction of the atomic-like absorption are realized: (i) by a spline drawn through the knots varied to minimize the low-r EXAFS FT part; (ii) by a smoothing spline and (iii) by a Bayesian smoothing curve.

This EXAFS database, which consists of just about every scan of data ever taken by Farrel Lytle, is a service of the International X-ray Absorption Society. The site is hosted by the Center for Synchrotron Radiation Research and Instrumentation at Illinois Institute of Technology. EXAFS is one of the most active ones.

The structures of the solvated copper(II) ion in water and nine organic oxygen donor solvents with similar electron-pair donor ability, but with different space-demandin X-ray absorption spectroscopy (XAS) is a widely used technique for determining the local geometric and/or electronic structure of matter. The experiment is usually performed at synchrotron radiation facilities, which provide intense and tunable X-ray beams. WINXAS is an EXAFS analysis suite for MS Windows 3.1 and later written by T. Ressler. Follow this link to the WINXAS home page.
