The influence of elastic strains, such as will arise around regions in a glass that have undergone an arbitraryvolume expansion, on the components of scattered light of various polarizations is calculated here. Theresults show that the effect of strains on the scattered intensities can be experimentally separated from theinfluence of size and shape of the scattering regions. Data on scattering from neutron-damaged vitreous silicaare analyzed. The strain scattering is well described by assigning a reasonable value to an optical parameterthat appears in the theory. Examination of that component of scattered light associated with the size andshape of the damaged regions reveals some peculiarities perhaps explicable in terms of a wide separation ofdamaged regions produced by a single primary recoil atom.
