α+Li and H+Be decay of 10,11,12B -: art. no. 044320

A study of the alpha+Li-6, alpha+Li-6(*), d+Be-8 and p+Be-9 decay of B-10, the alpha+Li-7, t+Be-8, and d+Be-9 decay of B-11 and the alpha+Li-8 and t+Be-9 decay of B-12 has been performed using the C-12(Li-7, B-10(*))Be-9, O-16(Li-7, B-10(*))C-13, Li-7(Li-7, B-11(*))t, and Li-7(Li-7, B-12(*))d reactions at 58 MeV. The excitation energy of the B-10,11,12(*) was determined following the coincident detection of the alpha+Li and H+Be decay fragments. A study of the relative yields for the decay of a number of excited states in B-10,11,12(*) indicates that the alpha-decay channel dominates in all cases.
