An Investigation of the Neutron Groups from the Disintegration of Phosphorus by 8 MeV Deuterons

The energy spectrum and angular distributions of some neutron groups emitted from the bombardment of a thin phosphorus target by 8 MeV deuterons have been investigated. The Q value of this reaction is found to be 6.63 ± 0.08 MeV. New excited states in 32 S at 6.29, 7.28 and 8.23 MeV, with errors of ±0.10 MeV have been observed. Angular distributions of neutron group corresponding to the transition to the ground state and two excited states at 2.25 MeV and 3.81 MeV in 32 S are compared with theoretical curves calculated on the basis of Butler and Born approximation stripping theories. The angular momentum of the captured proton to these states is found to be 0, 2 and 0 respectively. In an appendix, R Huby and H C Newns discuss the interpretation of these results of the shell model.
