Abstract

Some results of a 29Si NMR study of neutron-irradiated crystalline and vitreous SiO2 are reported. The spin-lattice relaxation time is found to change markedly with increasing neutron dose. Pronounced changes are also observed in the shape and position of the magic-angle spinning NMR lineshape. The shift in peak position for the metamict state is associated with a decrease in oxygen bond angle, and this is related to the densificaction of the glass observed upon neutron irradiation.
