X-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...

متن کاملObservation of metal–insulator transition in Al–Pd–Re quasicrystals by x-ray absorption and photoemission spectroscopy
Using x-ray absorption and valence-band photoelectron spectroscopy ~PES! we investigated the electronic structures of icosahedral (i)-Al70Pd22.5Re7.5 quasicrystals ~QCs! with a 4.2 K/300 K resistivity ratio, r , ranging from 8.3 to 107 obtained under various annealing conditions. Our Al Kand Pd L3-edge x-ray absorption results show that the density of states, N(E), near the Fermi level, EF , ju...
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 کاملSurface Hardness Measurment and Microstructural Characterisation of Steel by X-Ray Diffraction Profile Analysis
An X-ray diffraction line will broaden considerably when steels change into martensitic structure on quenching. The results presented in this paper show that X-ray diffraction technique can be employed for a rapid and nondestructive measurement of hardness of hardened steel. Measurement on various quenched and tempered steels showed that the breadth of its diffraction peak increased with increa...
