摘要：

The C-12(C-12,Be-8+Be-8)Be-8 reaction has been studied with 18 beam energies from 82 to 120 MeV. The detection of four of the six final-state alpha-particles in an array of eight 16-element strip detectors permitted the full reconstruction of the reaction kinematics. O-16 excitation energy spectra spanning 19-40 MeV were measured, which provided evidence for O-16 excited states up to 35.1 MeV. Angular correlation analysis indicates the dominant spins are 6 and 8 (h) over bar, possibly extending to 10 (h) over bar at the highest excitation energies. The resulting energy-spin systematics are compared with the predictions of the alpha cluster model and cranked Nilsson-Strutinsky calculations.
