(a) The ratio of intensities from zero-loss energy-filtered and unfiltered PED patterns (with 34 mrad precession angle) for the [001] zone axis of Er2Ge2O7, indicating a significant variation in inelastic scattering in the diffraction pattern. (b) The calculated ratio of inelastic to elastic scattering as a function of elastic intensity. The increase at low intensity arises from the increase in the inelastic cross-section for lighter elements (contributing most to the weaker reflections). Reproduced from Eggeman et al.
