Experimental (open circles) and simulated (solid lines) ϕ-scans of the and 133 3-BD in GaSb crystal as a function of the polarization angle χ. Primary reflection: . Simulated curves were generated using equation (2) (see Appendix A) for the `out → in' position. The best-fit values of δT and ξ (for R2 = 1.334 and b′ = 0) are shown on the left-hand side of each scan. The number on the other side stands for the maximum intensity normalized by the base line, 1. Wavelength: 1.2998 Å (2θA ≃ 90°). After Morelhão & Kycia (2002). |
