Cluster Structure of Be-9 from He-3+ Be-9 Reaction

Popis výsledku v původním jazyce

The study of inelastic scattering and multi-nucleon transfer reactions was performed by bombarding a Be-9 target with a He-3 beam at an incident energy of 30 MeV. Angular distributions for Be-9(He-3, He-3) Be-9, Be-9(He-3, He-4) Be-8, Be-9(He-3, Be-7) He-5, Be-9(He-3, Li-6) Li-6 and Be-9(He-3, Li-7)(5) Li reaction channels were measured. Cross sections for channels leading to unbound He-5(g.s)., Li-5(g.s). and Be-8 systems were obtained from singles measurements where the relationship between the energy and the scattering angle of the observed stable ejectile is constrained by two- body kinematics. Information on the cluster structure of Be-9 was obtained from the transfer channels. It was concluded that cluster transfer is an important mechanism in the investigated nuclear reactions. In the present work an attempt was made to estimate the relative strengths of the interesting Be-8+n and He-5+alpha cluster configurations in Be-9. The branching ratios have been determined confirming that the He-5+alpha configuration plays an important role. The configuration of Be-9 consisting of two bound helium clusters He-3+He-6 is significantly suppressed, whereas the two- body configurations Be-8+n and He-5+alpha including unbound Be-8 and He-5 are found more probable.
