Abstract
Measurements of Raman scattering from vitreous silica (spectrosil) in the temperature range 12-1200Â 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 30Â 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.
