A STUDY OF THE ANGULAR DISTRIBUTIONS OF NEUTRONS LEADING TO THE GROUND STATE IN THE REACTION $sup 12$C($sup 30$He,n)*SUP $sup 14$O
A pulsed beam time-of-flight neutron spectrometer was used to study the neutrons emitted from a target of C/sup 12/ bombarded with singly ionized He/sup 3/ 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 Oil were compared with a double stripping theory, and good agreement was obtained with the theoretical prediction for transfer of zero orbital angular momentum. It is emphasized that the angular distributions alone are insufficient to distinguish between a stripping prceess or a direct knockout mechanism, but arguments are advanced which favor the former. On the assumption that the mechanism of the reaction is that of double-stripping, the results led to the assignment of a spin zero and even parity to the O/sup 14/ ground state. (auth)
