![[[Image of BaTiO3 DAFS
data at the (100) and (200) reflections]]](dafs.gif)
There were two reflections in the vertical scattering plane accessible within the geometrical constraints of the goniometer and which were sufficiently intense to measure with a few hours of data collection.
Fortunately, the crystallographic structure of BaTiO3 is such that two reflections are sufficient to separate the contributions of the two resonant atoms.
Notice that the Ti cusp in the (100) reflection points up while the (200) cusp points down. This phase difference makes the the DAFS separation of the two resonant spectra possible.
Similar data were also collected at 128K and 300K.
