Description
The 12B excitation energy spectrum has been obtained from coincidence measurements of the 9Be + 7Li → 2α + 8Li reaction at E0 = 52 MeV. The decay of the states at excitations between 10 and 16 MeV into α + 8Li has been observed for the first time. Observed alpha-decay indicates possible cluster structure of the 12B excited states. The influence of these states on the cross-section of the astrophysically important 8Li(α,n)11B and 9Be + t reactions is discussed and the results are compared with existing results. (authors)
