Many-electron singularity in X-ray photoemission and X-ray line spectra from metals
It is pointed out that the spectra of x-ray induced fast photoelectrons from metal should have a characteristic skew line shape resulting from Kondo-like manyelectron interactions of the metallic conduction electrons with the accompanying deep hole in the final state. The same line shape should also occur for the discrete line spectra of x-rays emitted from metals. This mechanism could account ...
متن کاملHigh-resolution X-ray emission and X-ray absorption spectroscopy.
In this review, high-resolution X-ray emission and X-ray absorption spectroscopy will be discussed. The focus is on the 3d transition-metal systems. To understand high-resolution X-ray emission and resonant X-ray emission, it is first necessary to spend some time discussing the X-ray absorption process. Section II discusses 1s X-ray absorption, i.e., the K edges, and section III deals with 2p X...

متن کاملX-ray Absorption Spectroscopy
X-ray absorptioń spectroscopy, today widely used as a tool for structural investigations, is described. Theoretically it is shown that above an absorption edge the absorption coefficient is well approximated by a sum of terms, each one describing a particular path followed by the photoelectron outgoing from the atom. Such geometrical feature allows to use X-ray absorption spectroscopy for struc...
