Figure 4
(a) (0kl) plane of TDP at 180 K. Reflections with k = 2n + 1 are absent owing to pseudosymmetry. Reflection splitting reveals two ferroelastic domains. Their b* and c* axes are sketched. (b) Enlargement of the marked area showing domains slightly disoriented. Spots 1 and 2 belong to two domains related by a plane perpendicular to cort; 3 and 4 come from two domains related by a plane tilted (with respect to that relating 1 and 2) ∼2° around aort.
