Comparison of the (0kl) layer between experiment and theory. (a) Experimental data from the synthetic NaCl crystal at room temperature recorded in one orientation. Contour lines are guides for the eye for the shape of the Bragg peaks at the base of the peaks. (b) Computation of phonon excitations and (c) thermal diffuse scattering in the quasi-static approximation. Views (d), (e), (f) correspond to (a), (b), (c) for the same NaCl specimen in a different orientation as described in the text. The numbers in (c) and (f) refer to the detector bank contributing to this section and correspond to the labelling in Fig. 2. |
