Abstract
The efficiency of the application of the transmission X-ray diffraction technique implemented with the use of the VEPP-3 synchrotron radiation source to obtain functions of the radial electron density distribution (REDD) is shown. By the example of a poorly crystallized sample of cerium oxalate the possibilities of the obtained REDD functions in the structural diagnostics of X-ray amorphous materials are demonstrated: the oxalate phase is detected, the features of the local structure are revealed, and the size of the atomic ordering region is determined.
