We have investigated the light scattering behavior of Saturn's outer B ring at the 0.49-μm wavelength of the Voyager imaging system's clear filter. We study four types of radial regions: relatively bright and dark areas within, and outside of, the “spokes.” We model our data with a classical radiative transfer code which considers the illumination of the rings by the Sun and by Saturn. We find that the B ring particles have a strongly backscattering phase function similar to that of the satellite Callisto, suggesting the presence of a regolith on the surface of the ring particles. The large particle (spherical) albedo is 0.54 in the dark B ring regions and 0.58 in the bright regions. We interpret these albedos as the result of multiple scattering among very pure ice grains which cover the surfaces of the ring particles. The B ring regious outside the spokes appear to contain very little free submicron “dust,” a result with important implication for theories of ring composition and evolution. In the spokes, the fractional dust optical depth is about 1–2%, considerably less than previously believed. The radii of the spoke particles themselves cannot be uniquely determined due to the limited high phase angle coverage available. Finally, we show that impacts of dark micrometeroids into the B ring should have darkened the particles to their present spherical albedo in only about 1–2 × 10 8 years, and discuss this result in relation to other, previous arguments for a young ring age.
