The Debye-Waller (DWF) and Lamb-Mossbauer (LMF) factors for two representative glasses (methanol and selenium) are discussed. The wave vector dependence of the coherent functions shows the presence of noticeable fine structure. In particular, a maximum in the Q-dependence of the DWF at wave vectors well below Qp is shown. An assessment on the effects of internal, low-frequency motions on LMF derived from incoherent quasi-elastic scattering is also made.
