Cluster Structure of $^9$Be by Scattering of Deuterons

International audience; Angular distributions of protons, deuterons, tritons and alpha particles emitted in the reaction 2H+9Be at Elab=19.5 MeV were measured with an aim to shed light on the internal cluster structure of 9Be and to study possible cluster transfer of 5He. The analyses suggest a significant contribution of five-nucleon transfer in the reaction channel 9Be(d,4He)7Li.
