Figure 6
Calculated diffuse scattering patterns (upper semi-circles) compared with the corresponding observed X-ray data (lower semi-circles). (a) 0kl section; (b) hk0 section. [Note the upper and lower halves are not related by m symmetry. 0kl has twofold symmetry; hk0 has sixfold symmetry. It should also be noted that the calculated patterns contain no actual Bragg peaks since the average structure is subtracted during the calculation]. |
