摘要：
QENS spectra from 52% H2O-hydrated collagen fibres (T = 276-321 K) were modelled by three-component scattering laws including small central peak broadenings. These give diffusion coefficients for mobile H2O of similar to 5 x 10(-6) cm(2)/s, with activation energy similar to 2 kcal/mol. The broad components relate to Localised modes.
