Intermediate width structures in the 12C(12C,8Beg.s.)16O reaction at E c.m. =20 to 30 MeV

Abstract

The 12C(12C,8Beg.s.)16O reaction cross section has been measured at center-of-mass energies between 20 and 30 MeV. Intermediate width structures have been observed for the reactions leading to the ground state and two doublets of states, 6.05/6.13 MeV and 6.92/7.12 MeV, in 16O. For the 8Beg.s.+16Og.s. channel the dominant angular momenta contributing to several structures have been deduced by the analysis of the excitation functions at selected center-of-mass angles. Correlations between the structures in the 8Beg.s.+16Og.s. channel and in other inelastic scattering channels in the E c.m. = 30 MeV region are discussed. An interpretation of the resonances in terms of current structural models is given
