Abstract

Fluorescence techniques of recording EXAFS spectra are considered: XEOL and fluorescence EXAFS. The main causes of spectra distortions induced by both experiment conditions and mechanisms of luminescence's appearance under the action of synchrotron radiation. The algorithms of correction of experimental spectra to compensate for distortions are considered. By the example of alkali-halide crystals, it is demonstrated that, as the spectrum is recorded, radiationinduced transformations of the structure can occur in the sample. These transformations are not brought out in EXAFS spectra, but are detected by the XEOL method.
