The Angular Distribution of D-D Neutrons scattered by Deuterons

Abstract

The angular distribution of D-D neutrons scattered by deuterons has been investigated using a Wilson cloud chamber. The apparatus and experimental procedure, and the method of selecting and reducing the observations, is described. Comparison of the result with the calculations of Buckingham and Massey(3) indicate better agreement with the distribution to be expected assuming ordinary forces than with that assuming exchange forces.
