Depending on the particle size the light-scattering pattern exhibits minima and maxima. Because of the usual limitation in the angular resolution of the detection apparatus, the angular positions of these extrema remain fixed for intervals of values of the index of refraction of the shell, the size parameter of the whole particle, and the relative size of the core. These intervals are different for different extrema. For the set of particles represented by the fixed value of the angular position of a minimum, the relative perpendicular intensity at the minimum is plotted against the ratio of the radius of the core to the surface area of the entire particle; the curves form approximately one single curve for a range of values of the index of refraction of the shell. When the scattering pattern does not exhibit any minimum, choosing arbitrarily an angular position, the analysis has similar results. The results are illustrated by taking a typical swollen latex particle: the case when the core is polystyrene and the shell is a mixture of polymer and solvent. (1994 Academic Press, Inc.

The conference series is the superposition of two coherent series whose sources originated in Amsterdam (1995) and Bremen (1996). It covers all aspects of single and multiple light scattering by non-spherical particles. Following the series format, ample time for discussions were scheduled during t
Heterocoagulation of large and small oppositely charged colloid particles, accompanied by spreading of small beads over the surface of large spheres, offers a promising alternative to synthesis of core-shell particles via interfacial polymerization. In this paper, conditions required for complete sp
