Figure 5
Electron diffraction patterns of uvarovite, Ca3Cr2(SiO4)3, space group Ia[\bar3]d, a = 11.99 Å, with precession (a) off and (b) on. (c) Simulated diffraction pattern, using the kinematical approximation. Notice the effects of dynamical diffraction in (a); all reflections have nearly the same intensities. In contrast, the precession pattern (b) is very close to the kinematically calculated one in (c). After Gemmi & Nicolopoulos (2007BB24).
