Phase determination by polarized dispersion in vanadyl sulfate pentahydrate

Anomalous-scattering tensors for V measured with linearly polarized synchrotron radiation in VOSO₄.5H₂O near the K-absorption edge exhibit anisotropy as much as 4 units in f'' and ± 2 units in f'. This polarized dispersion causes the diffraction intensity to change when a crystal is turned around a diffraction vector and is the basis of a new way to obtain phases of structure factors.
