Abstract
A pulsed beam time-of-flight neutron spectrometer has been used to study the neutrons emitted from a target of 12C bombarded with singly ionized 3He particles having energies of 4.09, 4.62, 5.16 and 5.70 MeV. The angular distributions of the neutron group leading to the ground state of 14O have been compared with a double stripping theory, and good agreement has been obtained with the theoretical prediction for transfer of zero orbital angular momentum. It is emphasised that the angular distributions alone are insufficient to distinguish between a stripping process or a direct knock-out mechanism, but arguments are advanced which favour the former. On the assumption that the mechanism of the reaction is that of double-stripping the results lead to the assignment of a spin zero and even parity to the 14O ground state.
