Figure 10
Dolling's dispersion curve for the [100] direction in silicon (solid lines) and the loci of allowable ω and Q values (dotted lines) on D22 with a sample-to-detector distance of 1.5 m. The upper and lower dotted lines correspond to scattering angles (2θ) of 0 and 24.3°, respectively. The boundaries of the experimentally determined maximum and minimum energy are indicated by the dot–dash lines. |
