Abstract
This is an experimental study of multiple scattering by a polystyrene latex whose particles have a modal diameter of 1.277 μ. A special rectangular cell was constructed to correspond to an infinite plane-parallel slab. The experiments were carried out for two wavelengths, λ0=0.546 and 0.436 μ, for two cell thicknesses 0.089 and 0.183 cm, and for seven concentrations, ranging from 1.051×10−5 to 1.058×10−2 g/g. The angular range was from 0° to 90°. The higher angles were made accessible by placing the scattering cell in a cylindrical jacket containing Nujol. Extensive theoretical calculations were carried out with the aid of the Hartel theory for each of the above cases. The agreement between the experimental and theoretical results was excellent.
