Hyper-Raman scattering analysis of the vibrations in vitreous boron oxide
G. Simon, B. Hehlen, R. Vacher +1
Hyper-Raman scattering has been measured on vitreous boron oxide, BO. This spectroscopy, complemented with Raman scattering and infrared absorption, reveals the full se…
Hyper-Raman scattering from vitreous boron oxide: coherent enhancement of the boson peak
G. Simon, B. Hehlen, E. Courtens +2
Hyper-Raman scattering spectra of vitreous BO are reported and compared to Raman scattering results. The main features are indexed in terms of vibrations of structural unit…
Anharmonic vs. relaxational sound damping in glasses: II. Vitreous silica
R. Vacher, E. Courtens, M. Foret
The temperature dependence of the frequency dispersion in the sound velocity and damping of vitreous silica is reanalyzed. Thermally activated relaxation accounts for the sound att…
Anharmonic vs. relaxational sound damping in glasses: I. Brillouin scattering from densified silica
E. Rat, M. Foret, G. Massiera +4
This series discusses the origin of sound damping and dispersion in glasses. In particular, we address the relative importance of anharmonicity versus thermally activated relaxatio…
