n−dScattering at 2.45 and 3.27 Mev

Complete angular distributions for the elastic scattering of neutrons by deuterons have been obtained at 2.45 and 3.27 Mev by direct observation of the scattered neutrons using a time-of-flight technique, and results are given with a probable error of less than 3%. No support is found for the strong forward scattering indicated by a previous cloud-chamber experiment. The theoretical predictions of Buckingham, Hubbard, and Massey are in closer agreement with this experiment than are those of Christian and Gammel. $n-d$ scattering is found to be very similar to $p-d$ scattering at the same incident energy.
