[査読有り][通常論文] Heavy-ion resonances recently discovered in nuclear collisions of C-12+C-12 and O-16+O-16 systems leading to multi-cluster exit channels, C-12+C-12 --> 3 alpha+C-12, 3 alpha +3 alpha, 2 alpha+O-16 and O-16+O-16 --> (alpha+C-12)+O-16, (alpha+C-12)+(alpha+C-12), are studied theoretically by the coupled-channel (CC) and coupled-channel Born approximation (CCBA) calculations using microscopic cluster-model wave functions of the colliding nuclei, C-12 and O-16, and nucleus-nucleus interactions based on the realistic G-matrix interaction. These resonance states correspond to highly excited states of the compound systems, Mg-24 and S-32 nuclei, at excitation energies more than 40 similar to 55 MeV. The the microscopic CC and CCBA calculations well reproduce the characteristic features of these new resonance states.
