The structure of synthesized ferroelectric samples of PbSc0.5Ta0.5O3 after mechanoactivation were studied by means of X-ray absorption spectroscopy(XANES), X-ray diffraction (XRD) and scanning electron microscopy (SEM). Based on the combination of effective experimental methods and computer modeling of theoretical X-ray absorption spectra near the L3 - edge of tantalum and lead was studied character of structural distortions for investigated samples after mechanoactivation.
