The {sup 12}C({sup 12}C,{sup 8}Be+{sup 8}Be){sup 8}Be 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. {sup 16}O excitation energy spectra spanning 19-40 MeV were measured, which provided evidence for {sup 16}O excited states up to 35.1 MeV. Angular correlation analysis indicates the dominant spins are 6 and 8 ({Dirac_h}/2{pi}), possibly extending to 10 ({Dirac_h}/2{pi}) 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.
