The use of neutron resonance scattering in the structure determination of Sm(BrO₃)₃.9H₂O

The structure of Sm(BrO₃)₃.9H₂O has been solved by the neutron anomalous-dispersion method, with the use of data collected at two wavelengths. Five out of eight atoms in the asymmetric unit were located from the `anomalous difference Patterson' synthesis, and the remaining three from a Fourier synthesis. The structure is centrosymmetric, and the signs of 78% of the reflections were determined correctly from the differences in the Fobs values at the two wavelengths.
