The light scattering by an ensemble of monodisperse spatially correlated optically soft spherical particles is studied in the interference approximation. A model of the interaction of particles is proposed in which the spatial correlation between particles is determined by a radius Rc exceeding the particle radius Rp. The radial distribution function is calculated in the Percus-Yevick approximation for hard spheres of the radius Rc. To simulate the radiation scattering from an individual particle of the radius Rp, the Mie equations are used. It is shown that, in a medium of correlated small nonabsorbing particles of the radius Rc > Rp, an abnormal wavelength dependence of the refractive index is possible at a low volume concentration of particles. The results obtained explain some experimentally observed features of the scattering in sodium borosilicate glasses with a small concentration of scattering centers.
