ANOMALOUS SCATTERING AND DAFS MEASUREMENTS OF SMALL SINGLE-CRYSTAL OF BARIUM PLATINUM OXIDE

Anomalous diffraction and DAFS (diffraction anomalous fine structure) are X-ray techniques combining the short range structure sensitivity of X-ray absorption spectroscopy with the long range periodicity of X-ray diffraction. These techniques are demonstrated on a small single crystal of barium platinum oxide. Anomalous scattering factors f' and f'' are calculated and an accurate absorption correction procedure for a small concentrated single crystal is presented.
