Reactions induced by 30 MeV 3He beam on 9Be: Cluster transfer reactions

Abstract

An experiment has been carried out for studying the cluster structure of 9Be induced by the 3He ions at the energy of 30 MeV. As results of the nuclear reaction 3He + 9Be the differential cross sections for the exit channels - elastic, inelastic, α + 8Be, 6He + 6Be, 6Li + 6Li, and 7Be + 5He - were measured. Elastic and inelastic scattering data are treated within both the optical model and Coupled channels method. A new set of optical potential was taken for the elastic scattering. The deformation parameter δ2 was established for the transition 3/2→5/2. Cluster transfer reactions are analyzed by means of the coupled reaction channels method. The nuclear reactions with the exit channels 6He + 6Be, 6Li + 6Li, and 7Be + 5He are complemented by two-step transfer mechanisms. The contribution of each reaction mechanisms are shown, and compared with the findings of other authors.
