Figure 10
(a) SAED, (b) CBED and (c) a montage of 35 D-LACBED patterns taken from [110]PC NaBiCaTeO6. Gjønnes-Moodie dark crosses again mark the presence of a 21 axis along [[{\overline 1}10]]PC and a ([{\overline 1}10])PC mirror-glide plane. The whole-pattern symmetry is 2mm and the projection diffraction group is 2mm1R.  [article HTML]
