Abstract
The combination of x-ray Brillouin scattering data with coherent inela stic neutron scattering results in vitreous silica allows us to identi fy the scattering mechanisms for high-frequency sound waves in the gla ss. Below one THz, one has resonant scattering from low-frequency vibr ations, above one THz Rayleigh scattering from the atomic disorder.
