Abstract

Measurements of the He-4(Be-7, alpha)Be-7 and He-4(Be-7, p)B-10 reactions were performed using Be-7 beam energies of 7.1 and 23 MeV and a helium-4 target, employing the thick target technique. Resonances were observed between E-x(C-11) = 8.6 to 13.8 MeV. An R-matrix analysis was performed to characterize the spins and partial widths. This analysis showed that the observed sequence of states was consistent with that found for Li-7 + alpha resonant scattering populating resonances in B-11. A comparison of the proposed partial widths for decay with the Wigner limit indicates that several of the states are associated with cluster-like structures.
