Quasi-elastic scattering in vitreous silica: A Raman and neutron scattering study
Quasi-elastic scattering in vitreous silica: A Raman and neutron scattering study
Measurements of Raman scattering from vitreous silica (spectrosil) in the temperature range 12-1200 K are analyzed and compared with inelastic neutron scattering measurements done on the same sample. The results show a temperature dependence of the quasi-elastic scattering. Comparing this study with...

Measurements of Raman scattering from vitreous silica (spectrosil) in the temperature range 12-1200 K are analyzed and compared with inelastic neutron scattering measurements done on the same sample. The results show a temperature dependence of the quasi-elastic scattering. Comparing this study with acoustical attenuation measured at 30 GHz by Brillouin light scattering, we found that the mechanism giving rise to quasi-elastic scattering in vitreous silica seems to be the same as the one causing the acoustic attenuation.
