Abstract

To determine the effects on total light scattering of deep holes in the scattering particles, the Rayleigh-Gans-Debye and anomalous difffraction equations were solved by numerical methods for x = 0.1–1200, n = 1.05. Scattering by randomly oriented spheres with holes was compared with that from homogeneous smooth ones of equal net volume and refractive index. The effects of hole formation are found to be similar to those of projection formation that were previously reported. They also resemble those of uniform particle swelling with no change in mass. The results indicate that the influence of detail formation on total scattering is caused primarily by changes in the overall radial distribution of the mass, not by the generation of scattering centers.
