The crossover from propagating to strongly scattered acoustic modes of glasses observed in densified silica
E. Courtens, M. Foret, B. Hehlen +2
Spectroscopic results on low frequency excitations of densified silica are presented and related to characteristic thermal properties of glasses. The end of the longitudinal acoust…

Observation of the onset of strong scattering on high frequency acoustic phonons in densified silica glass
B. Ruffle, M. Foret, E. Courtens +2
The linewidth of longitudinal acoustic waves in densified silica glass is obtained by inelastic x-ray scattering. It increases with a high power alpha of the frequency up to a cros…
