摘要：
A study of the C-12(Mg-24,(CC)-C-12-C-12)C-12 reaction has revealed discrete states at excitation energies between 20 and 30 MeV in Mg-24. Angular correlation analyses of some of the lower energy states confirms the report by earlier authors of monotonically increasing spin values consistent with a rotational sequence. Comparison with breakup observed in the C-12(Ne-20,(CC)-C-12-C-12)Be-8 reaction suggests that the same states in Mg-24 are populated, while the difference in laboratory cross sections in the two reactions is interpreted as evidence for the association of the breakup states with a prolate hyper-deformed configuration appearing in theoretical calculations for Mg-24.
