Abstract

An approach is proposed for evaluation of an asymmetry parameter for anomalous scattering of light in nanostructured glasses from the experimental wavelength dependence of the scattering coefficient. This dependence observed for phase-separated glasses and glass-ceramics is described by the power law with the constant exponent ($-p$), where $p$ is greater than 4. In the approach, the material is modeled by identical Rayleigh scatterers distributed in a homogeneous matrix. We use this model, the interference approximation for a scattering coefficient and its experimental wavelength dependence, and express the asymmetry parameter in terms of $p$. The results can be applied to the simulation of multiple light scattering in nanomaterials.
