In the lattice-translocation defect crystals, every other layer is either in the Fig. 5b orientation (see static image below) or in the Fig. 5d orientation, and the choice is absolutely random. | In the lattice-translocation defect crystals, every other layer is either in the Fig. 5b orientation (see static image below) or in the Fig. 5d orientation, and the choice is absolutely random. | ||

This randomness breaks the long-term periodic and forms a local short-term periodic. This appears to be the particle-size broadening (Coppens, 1997)<ref name="Coppens">PMID:25727874</ref>. If the long-term periodic is broken, the diffraction intensity would spread along the reciprocal-space direction of the step function. In this special case, it is the b* direction. With the spread of the reflections, the subsidiary maxima of the neighboring reflections may overlap, which will result in the smear spots, the especial chacteracters of LTD. | This randomness breaks the long-term periodic and forms a local short-term periodic.
