Experimental polycrystalline S′(Q, ω) for aluminium at 10 K obtained on the MARI spectrometer, ISIS, for the full range in neutron energy loss 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 (yellow) to very high (dark red). White areas denote regions in (Q, ω) space where there is no detector coverage. |
