The Raman coupling function in disordered solids: a light and neutron scattering study on glasses of different fragility

Abstract

We report new inelastic Raman and neutron scattering spectra for glasses with different degrees of fragility; the data are compared for each sample to obtain the Raman coupling function $C(\omega )$. The study indicates a general linear behaviour of the $C(\omega )$ near the Boson peak maximum, and evidence a correlation between vibrational and relaxational properties, already observed in recent publications.
