Figure 3
(a) 2D symmetric θ/θ scan with the scattering vector perpendicular to the apparent fibre axis. (b) 2D frame scanned from this geometry showing only 0kl Debye arcs. (c) (0kl) planes in the gypsum unit cell and their common parallel fibre texture axis: 〈100〉 marked with `⊗'. The fibre texture of crystals can be represented by spinning the unit cell around its a axis, where each rotation represents a crystal orientation. |
