The C-12(C-12,Be-8+C-12(0(2)(+)))He-4 reaction has been studied with beam energies of 82-120 MeV to search for excited states in Ne-20 that decay into Be-8+C-12(0(2)(+)). The detection of five of the six final-state alpha particles in an array of eight, sixteen-element, strip detectors permitted the full reconstruction of the reaction kinematics. Two Ne-20 resonances at 35.2 and 36.5 MeV are observed, particularly at beam energies less than 93 MeV. An analysis of the angular correlations associated with the observed resonances indicates that an angular momentum of 10 h is important in this region, and thus it is possible that at least one of the resonances possesses J(pi)=10(+).
