Mishchenko, M.I., and J.M. Dlugach, 1993: Coherent backscatter and the opposition effect for E-type asteroids. Planet. Space Sci., 41, 173-181, doi:10.1016/0032-0633(93)90056-8.

Recently, Harris et al. (Icarus 81, 365-374, 1989) have observed a strong and unusally narrow (HWHM ≃ 0.8° in the yellow) opposition effect for high-albedo asteroids 44 Nysa and 64 Angelina. In this paper, we apply the theory of coherent backscattering of light from discrete random media to interpret this remarkable opposition brightening. It is shown that coherent backscattering of sunlight from a regolithic layer composed of submicrometer-sized grains with an index of refraction close to that of the mineral enstatite can be a reasonable explanation of the observed opposition effect.
