LIGHT SCATTERING IN SILVER SOLS.

Abstract

The intensity of the transversely scattered light has been measuredat different wave-lengths for six typical silver sols using a photomultiplier.Applying Gans' theory for small ellipsoidal particles in metallic sols,the intensities of scattering have been calculated for different axial ratios B/A of a small prolate ellipsoid of silver and compared with the experimentaldata. The relative sizes as well as the degree of departure fromspherical shape for the particles present in the different sols have beenestimated. A comparison has also been made between the absorptionand intensities of scattering at different wave-lengths.
