Abstract
Anderson, Brumberger and Marchessault have published photographic light scattering patterns from poly-L-alanine spherulites1 which show the four-leaf clover type Hν pattern (vertically polarized incident light with horizontal analyser) experimentally found for polyethylene and other spherulitic polymers2. Patterns of this sort have been predicted by the theory of scattering from spheres2 and disks3,4.
