摘要：

We have measured the energy and polarization dependence of anisotropic resonant x-ray Bragg diffraction from cubic HoFe2 at glide-reflection-forbidden settings. Azimuthal scans at the iron K-edge are found to be consistent with calculations based on purely dipolar transitions. The possible influence of magnetic scattering is discussed, and we set out a simple procedure for calculating resonant intensities, based on crystal symmetry.
