We have measured the vibrational density of states (VDOS) of normal and densified vitreous silica by means of neutron scattering for the first time. We have also observed Raman spectrum to find the densification dependencies. Neutron VDOS does not change drastically on densification, except for an e

The decrease of the mean Si-O-Si angle in vitreous silica upon densification from 2.20 to 2.36 gcm -3 has been followed by oxygen and silicon K-edge XANES spectroscopy. Multiple scattering calculations using clusters of two shells around the oxygen and silicon atoms, respectively, are in good agreem
