摘要：

The breakup of Be-12 into He-6 + He-6 and He-4 + He-8 has been studied using a 378 MeV Be-12 beam inelastically excited by C-12 and (CH2)(n) targets. The measurements indicate that breakup occurs from rotational states in the 10 to 25 MeV excitation energy interval, with spins in the range of 4(h) over bar to 8(h) over bar. The inferred moment of inertia is consistent with the cluster decay of an exotic molecular structure in Be-12, which may be associated with an alpha-4n-alpha cluster configuration.
