X-Ray Absorption Fine Structure - an overview - ScienceDirect

WebThe word "stimulated" means that the emission of the photon is "encouraged" by the existence of photons in the same state as the state where the new photon may be added. The "same state" is one that has the same frequency, the same polarization, and the same direction of motion. WebThus, EXAFS provides structural information with electron resolution but using photons as the observable. In EXAFS, a significant increase in X-ray absorption is observed when the energy of the incoming photon is equal to or greater than the binding energy of a core-shell electron, commonly referred to as an absorption edge, as shown in Fig. 17 ...

WebThe photoelectric effect is a common interaction between a low-energy photon and a material. In this process the photon interacts with an electron in the material losing all of its energy. The electron is ejected with an energy equal to the initial photon energy minus the binding energy of the electron. WebAs shown in Fig. 2, the interaction between an electron and a photon results in the electron being given part of the energy (making it recoil), and a photon of the remaining energy …
