States in 12B and primordial nucleosynthesis. (II). Resonance properties and astrophysical aspects
The 9Be(α, p)12B has been used to populate states which could correspond to astrophysically significant resonances in the 8Li(α, n)11B reaction. The branching ratios for neutron decays have been measured and the neutron angular distributions have been used to determine Jπ 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. © 1994.
