  1. X-ray absorption fine structure - Wikipedia

    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 …

  2. Fundamentals of XAFS - Argonne National Laboratory

    XAFS is an element-speci c spectroscopy in which measurements are made by tuning the X-ray energy at and above a selected core-level binding energy of a speci ed element.

  3. Specifically, XAFS is the modulation of an atom’s x-ray absorption probability due to the chemical and physical state of the atom. XAFS spectra are especially sensitive to the formal oxidation …

  4. AFS Chicago, Illinois Introduction Over the last two decades X-ray Absorption Fine Structure (XAFS) spectroscopy has emerged as an incisive probe of the local structure around selected …

  5. 7.6: XAFS - Chemistry LibreTexts

    X-ray absorption fine structure (XAFS) spectroscopy includes both X-ray absorption near edge structure (XANES) and extended X-ray absorption fine structure (EXAFS) spectroscopies.

  6. X-ray Absorption Fine Structure (XAFS) | NIST

    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 …

  7. New To XAFS | easyXAFS

    What is X-ray Absorption Spectroscopy? X-ray absorption spectroscopy (XAS) is an analytical technique that relies on the variable absorption of x-rays by matter to probe its chemical state …

  8. X Ray Absorption Fine Structure Spectroscopy - ScienceDirect

    X-ray absorption fine structure (XAFS) spectroscopy is a premier technique for measuring both electronic and atomic local structures around different atomic species in materials. XAFS can …

  9. Fundamentals of X-ray Absorption Fine Structure

    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. XAFS is also referred to as X …

  10. XAFS can be interpreted as due to scattering of the photo-electron ejected from the absorbing atom by the photo-electric effect. Cross-section is a measure of the probability of interaction …
