During the manufacture of powder metal, the size distribution of the metal spheres can be determined to some extent by the distribution of light scattered by the spheres while they are streaming by a laser beam. Micrographs show the presence of chains of spheres and of spheres with a number of smaller spheres attached to them. It is of interest to compare the pattern of the radiation scattered by such agglomerates with the pattern produced by isolated spheres. An integral equation is used to compute the fields scattered by two perfectly conducting touching spheres when a plane monochromatic wave is incident from an arbitrary direction.
