We present a systematic study of the opposition effect, i.e., the nonlinear increase of reflected intensity at small phase angles. This phenomenon has been observed both in the phase curves of bright solar system objects as well as in laboratory and field measurements of bright materials. By solving the scalar radiative transfer equation for a plane-parallel medium by means of an optimized Monte Carlo simulation (see Muinonen, this meeting), a systematic computation of intensities at different combinations of parameters, such as single-particle albedo, optical thickness, and asymmetry parameter of the Henyey-Greenstein single-particle phase function has led to a large database of phase curves, enabling us to study the effect of coherent backscattering on the behavior of the narrow opposition effect of different materials, at different values of these parameters. We also present a set of field measurements of lake ice and two types of snow, as well as existing observations of Europa, with comparison to the calculations. The field measurements were performed in March 1999, the smallest phase angle being 0.06 degrees. The results seem to indicate the presence of the opposition effect.
