X-ray absorption fine structure (XAFS) is a specific structure observed in X-ray absorption spectroscopy (XAS). By analyzing the XAFS, information can be acquired on the local structure and on the unoccupied local electronic states.

Demeter is a comprehensive system for processing and analyzing X-ray Absorption Spectroscopy data. » Use the Ifeffit Mailing List « B. Ravel and M. Newville, ATHENA, ARTEMIS, HEPHAESTUS: data analysis for X-ray absorption spectroscopy using IFEFFIT, Journal of Synchrotron Radiation 12, 537–541 (2005) doi:10.1107/S0909049505012719.

Sep 14, 2017 · The XAFS station uses a tunable, monochromatic, and moderately high energy X-ray beam (4.5 keV to 23.5 keV) for X-ray absorption spectroscopy measurements. The energy of the incident beam is tuned to the binding energy of an element of …

What Is XAFS? X-ray Absorption Fine-Structure (XAFS) is the modulation of the x-ray absorption coefficient at energies near and above an x-ray absorption edge.

Extended X-ray absorption fine structure (EXAFS), along with X-ray absorption near edge structure (XANES), is a subset of X-ray absorption spectroscopy (XAS). Like other absorption spectroscopies, XAS techniques follow Beer's law.

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.

Apr 11, 1997 · X-Ray Absorption Fine Structure (XAFS) refers to modulations in x- ray absorption coefficient around an x-ray absorption edge. XAFS is often divided (somewhat arbitrarily) into "EXAFS" (Extended X-ray Absorption Fine Structure) …

XAFS is a spectroscopic technique that uses the absorption of X-rays to probe the physical and chemical structure of matter at an atomic scale. X-ray absorption spectroscopy is element-specific, in that X-rays are chosen to be at and above the binding energy of a particular core electronic level of a particular atomic species.

X-ray absorption fine structure spectroscopy (XAFS) is a powerful and versatile technique for studying structures of materials in chemistry, physics, biology, and other fields. This textbook is a comprehensive, practical guide to carrying out and interpreting XAFS experiments.
