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 کاملStrong X-ray Absorption in a Broad Absorption Line Quasar: Phl 5200
We present ASCA observations of the z 5 1.98 prototype broad absorption line quasar (BALQSO): PHL 5200. The source was detected in both SIS and GIS. A power-law spectrum (aE 5 0.620.6 10.9 ) with large intrinsic absorption (NH 5 1.321.1 12.3 3 10 cm) best describes the spectrum. Excess column density over the local Galactic value is required at the 99% confidence level. This detection suggests ...
متن کاملUltrafast dynamics of strong-field dissociative ionization of CH2Br2 probed by femtosecond soft x-ray transient absorption spectroscopy
Femtosecond time-resolved soft x-ray transient absorption spectroscopy based on a high-order harmonic generation source is used to investigate the dissociative ionization of CH2Br2 induced by 800 nm strong-field irradiation. At moderate peak intensities (2.0 × 10 W/cm), strong-field ionization is accompanied by ultrafast C–Br bond dissociation, producing both neutral Br (P3/2) and Br* (P1/2) at...
متن کاملX-ray Absorption Spectroscopy Using X–ray Fluorescence Spectrometer
Strong characteristic Kα X-ray lines are accompanied by weak lines due to the radiative Auger effect (RAE) [1, 2]. The characteristic Kα fluorescent X-rays (K-L2,3 lines) are emitted by the 2p→1s electric dipole transition after one of the 1s electron photoionization, Though the probability is less than 0.01, one of the 2p electrons is excited into an unoccupied discrete or continuum level simu...
