Abstract

We report new inelastic Raman and neutron scattering spectra for glasses with different degrees of fragility, v-SiO2, v-GeO2, (AgI)0.5(Ag2O-B2O3)0.5, (AgI)x(AgPO3)1-x. The data are compared for each sample to obtain the Raman coupling function C(ω). The study indicates a general linear behaviour of C(ω) near the boson peak maximum, and evidences a correlation between vibrational and relaxational properties, confirming the results of recent publications. © IOP Publishing Ltd.
