Multienergy anomalous diffuse scattering

Result description

A new approach to local structure determination is presented. A three-dimensional region of the reciprocal space of a SrTiO3 single crystal was mapped by measuring x-ray diffuse scattering patterns at different sample orientations in order to reconstructthe local atomic structure. The phase problem was solved by means of anomalous scattering from strontium atoms at photon energies near their K absorption edge. Real-space reconstruction provides the average short-range order atomic arrangement in the vicinity of anomalous scatterers up to a distance of several unit cells.

    Víceenergetický anomální difúzní rozptyl

  • Czech description

    Článek uvádí nový přístup k určování lokální struktury na atomové úrovni. Byl změřen difúzní rozptyl v trojrozměrné oblasti reciprokého prostoru monokrystalu SrTiO3. Z těchto dat byla rekonstruobvána atomová struktura. Fázový problém byl vyřešen pomocí anomálně roztylujících Sr atomů. Rekonstruovaný obraz v přímém prostoru odpovídá průměrnému atomovému uspořádání v okolí anomálně rozptylujích atomů v oblasti několika základních buněk.
