A complete kinematic measurement of the Li6(He3,H3)αpp reaction is performed at Elab=50MeV, to investigate the cluster structure of Be6. The energy and angular distributions of the breakup particles, emitted from the ground and first excited states of Be6, are compared to three-body resonance and two-body sequential decay calculations. The results indicate a rather pure three-body configuration of the 2+ state of Be6 but they are not conclusive regarding the decay mode of the 0+ state. No branching ratio between sequential and three-body decay paths could be extracted. Excitations above the 2+ state were populated at Ex=1.67-23MeV. Decay through Li5-p and He2-He4 channels is identified in the continuum of Be6, and the reaction mechanism is discussed.
