2. X-ray absorption spectroscopy - Wikipedia

   en.wikipedia.org/wiki/X-ray_absorption_spectroscopy

   X-ray absorption spectroscopy (XAS) is a widely used technique for determining the local geometric and/or electronic structure of matter. [1] The experiment is usually performed at synchrotron radiation facilities, which provide intense and tunable X-ray beams. Samples can be in the gas phase, solutions, or solids. [2]

3. X-ray absorption fine structure - Wikipedia

   X-ray absorption edge spectroscopy corresponds to the transition from a core-level to an unoccupied orbital or band and mainly reflects the electronic unoccupied states. EXAFS, resulting from the interference in the single scattering process of the photoelectron scattered by surrounding atoms, provides information on the local structure.

4. X-ray absorption near edge structure - Wikipedia

   en.wikipedia.org/wiki/X-ray_absorption_near_edge...

   X-ray absorption near edge structure (XANES), also known as near edge X-ray absorption fine structure (NEXAFS), is a type of absorption spectroscopy that indicates the features in the X-ray absorption spectra of condensed matter due to the photoabsorption cross section for electronic transitions from an atomic core level to final states in the energy region of 50–100 eV above the selected ...

   There exist several efficient designs for analyzing an X-ray emission spectrum in the ultra soft X-ray region. The figure of merit for such instruments is the spectral throughput, i.e. the product of detected intensity and spectral resolving power. Usually, it is possible to change these parameters within a certain range while keeping their ...

6. Extended X-ray absorption fine structure - Wikipedia

   en.wikipedia.org/wiki/Extended_X-ray_absorption...

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