    • For a non-Bravais lattice, the different contributions are weighted by functions of the masses, concentrations, scattering lengths, etc., such that the direct relationship between the vibrational DOS and the measured function is lost. Moreover, there are coherent contributions, which in principle distort the spectrum. In the monoatomic case, the DOS can still be measured provided we integrate over all of reciprocal space, but kinematical conditions prevent one from measuring in the region of reciprocal space where the phonon velocity is larger than the neutron velocity (see Figs. 3 and 4 of the first reference in Ref. In practice, one sums up by brute force the signals from all detectors and invokes a soothing argument that one has integrated over a large, unbiased and therefore representative slice of reciprocal space. [See, for example, F. Gompf, H. Lau, W. Reichert, and J. Salgado, in, (IAEA, Vienna, 1972), p. 137.]
