摘要：

The Be-9(alpha, p)B-12 has been used to populate stales which could correspond to astrophysically significant resonances in the Li-8(alpha, n)B-11 reaction. The branching ratios for neutron decays have been measured and the neutron angular distributions have been used to determine J(pi) for these states. This information, combined with previous measurements of excitation energies and total widths, allows us to extract the resonance strengths for these states. The astrophysical significance of these results is discussed.
