Light scattering by a prism and pyramid in the Rayleigh-Gans-Debye approximation

摘要

The general approach to finding the form factor of a compound particle and a system of particles in the Rayleigh-Gans-Debye (RGD) approximation is considered. The rotational-translational properties of light scattering amplitude in the RGD approximation are formulated. Using such properties, the analytical expressions for the amplitude of light scattering by a prism and pyramid with an arbitrary polygonal base in the RGD approximation are obtained. The phase functions of light scattering by a prism and pyramid in the RGD approximation are computed.
