New insight into the cluster structure of 9Be by reactions with deuteron beam

Abstract

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