Abstract

The light scattering technique of determining the radius of small spherical particles by measurement of the polarization ratio is extended to the case of nonmonochromatic light. The new method is applied to sulfur and dibutyl phthallate aerosols irradiated by an unfiltered beam from a mercury vapor lamp. The radii obtained with the unfiltered light are in agreement with those obtained when monochromatic light is used.
