Application of a band crossing model for resonances in high energyC12-C12scattering

Resonance phenomena observed in single and mutual $2_1^{+}$ inelastic scattering and in $3_1^{-}$ inelastic scattering in the ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$-${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ system are investigated using a band crossing model. It is shown that characteristic features of the observed resonances can be well understood and well reproduced by the model. The coupling between wide resonances is also discussed. Another important prediction of the model, i.e., transfer of the dominant components of resonances from single and mutual $2_1^{+}$ excitations to the $3_1^{-}$ excitation with increasing scattering energy appears to be realized. These facts support the validity of the band crossing model in this system. We conclude that the prominent correlated resonances observed in high energy inelastic ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$-${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ scattering can be considered as a strong evidence for the existence of nuclear molecular phenomena in this energy range.
