| Résumé | Incoherent-inelastic neutron scattering data are obtained from 5�80 K for high-density amorphous (hda) ice in the region 0�135 cm-1. An excess contribution to the vibrational density of states is identified near 20 cm-1. The origin of these vibrations has been identified by lattice dynamics calculations on an �experimental� structure derived from reverse Monte Carlo analysis of hda ice neutron diffraction data. An interpretation that localized oscillations of short chains and isolated water molecules are responsible for the excess low-frequency modes is consistent with our data. |
