Description
Full text of publication follows. Significant changes of spectra taken at the Nb K and LIII edges are observed after irradiating LiNbO3 with +3He ions (energy 40 MeV). Our XAFS study provides some insights into the structural changes that take place during the irradiation process. The measurements at the Nb LIII-edge support the assumption that there are changes in the geometrical structure. This result together with the performed FEFF8 calculations, done to simulate the Nb-K-XANES spectra, and the Extended X-ray Absorption Fine Structure (EXAFS) analysis suggest presence of Li vacancies and/or displacement of Li atoms.
