摘要：

The phonon dispersion in the second Brillouin zone of polycrystalline ice (1h) has been measured. The results confirm the predictions of a previous lattice-dynamics calculation [A. Criado, F. J. Bermejo, M. Garcia-Hernandez, and J. L. Martinez, Phys. Rev. E 47, 3516 (1993)] where anomalously steep dispersion curves of an apparent acoustic origin were found. The relevance of the present findings for explaining some apparently anomalous features concerning the collective dynamics of liquid water is finally discussed.
