Abstract

The quasi-elastic Raman scattering in SiO₂ and PS glasses is analyzed in the framework of the model of a damped oscillator. The model ascribes the quasi-elastic contribution to the scattering of light on damped vibrations which have a quasi-elastic part in their response function. With additional assumption that the vibrations around the boson peak are damped by the same process as the acoustic waves, a good agreement is obtained between acoustic attenuation data and QES spectra in SiO₂ and polystyrene both on a qualitative and a quantitative level.
