A complete kinematic measurement of the {sup 6}Li({sup 3}He,{sup 3}H)alphapp reaction is performed at E{sub lab}=50 MeV, to investigate the cluster structure of {sup 6}Be. The energy and angular distributions of the breakup particles, emitted from the ground and first excited states of {sup 6}Be, are compared to three-body resonance and two-body sequential decay calculations. The results indicate a rather pure three-body configuration of the 2{sup +} state of {sup 6}Be but they are not conclusive regarding the decay mode of the 0{sup +} state. No branching ratio between sequential and three-body decay paths could be extracted. Excitations above the 2{sup +} state were populated at E{sub x}=1.67-23 MeV. Decay through {sup 5}Li-p and {sup 2}He-{sup 4}He channels is identified in the continuum of {sup 6}Be, and the reaction mechanism is discussed.
