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
