Theoretical polycrystalline S′(Q, ω) for aluminium, calculated using the LJ 12–6 potential model, for the full range of Q (0 ≤ Q ≤ 10.0 Å−1) and ω (0 < ω < 350 cm −1). The S′(Q, ω) intensity rises from very low (dark blue) through mid (light blues and yellow) to very high (dark red). White areas denote regions in (Q, ω) space where no scattering occurs, whereas dark blue shows low-intensity scattering due to off-symmetry direction (polycrystalline averaged) scattering.
