Abstract

The resonant states in the key reaction8Li(α,n)11B for the inhomogeneous Big Bang Models were studied experimentally through the9Be(α,p)12B reaction at 64 MeV. This reaction is found to excite all the resonances of interest in12B. The most crucial resonant state at 10.572 MeV in12B (0.572 MeV above the α threshold) was found to have Γtot≤20±10 keV and Jπ=(1-), suggesting that the S-factor of the (α,n) process should be larger than that obtained before.
