REQUIREMENTS FOR X-RAY SPECTROSCOPY
Dirk Lützenkirchen-Hecht and Ronald Frahm Bergische Universität Wuppertal Wuppertal, Germany The basic process related to x-ray absorption spectroscopy (XAS, which includes x-ray absorption near edge spectroscopy, XANES, and extended x-ray absorption fine structure, EXAFS) is the absorption by an atom of a photon with sufficient energy to excite a core electron to unoccupied levels (bands) or to the continuum. An XAS experiment comprises the measurement of the absorption coefficient μ(E) in the vicinity of an absorption edge, where…
