Abstract
The scattering is analyzed at two levels in , one at 12.42-Mev excitation and the other at 12.60 Mev. The lower level is assigned as and the upper as . A nuclear radius is assumed and reduced widths are obtained for the two levels. With the aid of the reactions and (3.09-Mev level), partial level widths for the three modes of decay of are obtained. Both () reactions are shown to be consistent with the presence of stripping amplitudes and resonant compound nuclear amplitudes and also consistent with the + data of Shire et al. for the same excitation region in . The () angular distributions are analyzed to obtain the reduced neutron widths of the ground and first excited states of .
An appendix gives an explicit partial-wave expansion of the differential cross section for reactions involving incident spins of 0 and 1 and outgoing spins of ½ and ½.
