The interaction of an E/A=70-MeV 7Be beam with a Be target was used to populate levels in 6Be following neutron knockout reactions. The three-body decay of the ground and first excited states into the alpha+p+p exit channel were detected in the High Resolution Array (HiRA). Precise three-body correlations extracted from the experimental data allowed us to obtain an insight into the mechanism of the three-body democratic decay. The correlation data are in a nice agreement with a three-cluster-model calculation and thus validate this theoretical approach over a broad energy range.
