Figure 1
(a) The 0.5c* section of Ca-CSZ in the relatively low scattering-angle range sinθ/λ ≤ 0.67. The `dark lines' indicated by the arrows and the diffuse peaks enclosed in the white rectangle are referred to in the text. (b) The profile of the diffuse intensity along the [110] direction through these diffuse peaks (and including data extending out to sinθ/λ ≃ 0.97). The arrows indicate the asymmetry in intensity across the dark lines seen in (a). |
