SXD SINGLE-CRYSTAL DIFFUSE-SCATTERING - MORE THAN JUST A PRETTY PICTURE

The diffuse scattering from single crystals studied on the SXD single crystal time-of-flight Laue diffractometer provides not only a very beautiful visual image but also a very powerful source of structural information. Diffuse scattering results from deviations from the average structure, and is often difficult to interpret. No standard method exists which is suitable for analysis of the scattering from all crystals. Using the diffuse scattering from ice as an example the single crystal reverse Monte Carlo technique (RMCX), which is intended to be widely applicable, is discussed and the type of information obtainable using it considered.
