Abstract
The total-scattering coefficient and volume-scattering function of a log-normal distribution of red clay (mean diameter = 1.5 μ, variance = 1.5 μ2) was computed using Mie theory. A total-scattering coefficient of 0.1 (per meter) was found for an assumed suspended volume of 10−7cc per cc. Ninety per cent of the total scattering is due to particles between 0.5 and 8.5 μ diameter. The volume-scattering function is highly peaked in the forward direction with the half-power points of the forward lobe at 1 1/2°. Ninety per cent of the forward (1°) scattering is produced by larger particles in the range of 1.3 to 18.5 μ in diameter while at larger angles such as 90° the bulk of the effect is caused by particles in the size range of 0.2 to 6.5 μ in diameter. The peak polarization of 0.61 is observed at a scattering angle of 120°. The optical properties show little dependence on wavelength.
