Figure 3
Loci of allowable ω and Q values (solid lines) on D22 with a sample-to-detector distance of 1.5 m for neutron energy loss (phonon creation) or neutron energy gain (phonon annihilation). The left and right solid lines correspond to scattering angles (2θ) of 0 and 24.3°, respectively. The dot–dash lines are fits to the silicon dispersion curves for the [100] direction from Dolling (1963BB2).
