摘要：
The aim of this work is to provide a detailed description of resonant elastic scattering at the iron K edge in alpha-Fe2O3 (hematite), as recently probed by Finkelstein, Shen, and Shastri. This is achieved by developing a general, group-theoretic approach, which exploits point-group symmetry, scattering geometry, and polarisation. Extinction rules, their breaking, and the observation of forbidden reflections are also discussed.
