Notes:
High quality single crystals or thin films containing Mössbauer isotopes are the main x-ray optical component for nuclear Bragg scattering (NBS) with synchrotron radiation. For this purpose, flux grown α-57Fe2O3 (hematite) single crystals prepared in two growth runs have been characterized by plane wave x-ray topography, which indicated the most suitable sample. Measurements of (111), (333), (555), (777), and (999) pure nuclear-reflection profiles showed a good agreement of relative reflectivity with the values calculated from theory. At the beamline NE-3, accumulation ring of TRISTAN, a Mössbauer event rate as high as 13 000 cps for (777) reflection was observed.
