| Abstract | An X-ray absorption spectroscopist is usually interested in the energy range of 300 eV-30 keV. This is in stark contrast to optical spectroscopies where valence electron states are probed. In XAS (X-ray absorption spectroscopy) the relevant parameter of the photon is its energy and its “resolution”. After the absorption event, the photoelectron is emitted. This plays a key role in a microscopic understanding of the spectroscopy. It may be considered equally well as an energetic particle of energy E or as a wave of momentum k given by the free electron-like definition of its energy |
