Angular Distribution of Elastically Scattered Deuterons and Disintegration Protons from the Bombardment of Beryllium by 7.7 MeV Deuterons

The deuteron beam from the Liverpool 37 in. cyclotron was used to bombard a thin beryllium foil in a vacuum chamber The photographic plate method was employed in detecting the charged particles emitted from the reaction. The angular distribution of the elastically scattered deuterons shows a secondary maximum at 65°. Angular distributions of the two longest range proton groups are compared with the recent theories of the angular distributions of the (d, p) and (d, n) reactions. The results indicate that both ground state and first excited state of the residual nucleus 10 Be have even parity and spin either 0, 1, 2 or 3.
