ENERGY-DEPENDENCE OF THE O-16(O-16,C-12-ASTERISK)NE-20, C-12(O-16,C-12-ASTERISK)O-16 AND LI-7(O-16,C-12-ASTERISK)B-11 REACTIONS

Measurements of the energy dependence of the reactions O-16(O-16,C-12 )Ne-20, C-12(O-16,C-12)O-16 and Li-7(O-16,C-12*)B-11 been performed a t beam energies ranging from 51 to 66 MeV. Silicon strip detectors wer e used to detect the decays of C-12 nuclei excited to the 0(2)(+), 7.6 5 MeV and 3(-), 9.64 MeV excited states. Correlated, broad structures have been observed in the O-16(O-16,C-12)Ne-20 reactions at E(cm) = 2 7.5 and 32.0 MeV, with associated angular momenta of L = 18 and 20 res pectively. Similar structures have also been observed in the C-12(O-16 ,C-12)O-16 reactions at E(cm) = 24.5 and 26.5 MeV, with associated an gular momenta of L = 12 and 13.
