Resonance in the Two-Nucleon Transfer ReactionC12(C12,B10)N14

The energy dependence of the reation ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$(${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$,${}_{}{}^{10}{}_{}{}^{}\mathrm{B}$)${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$ has been studied in the range $E_{\mathrm{c}.\mathrm{m}.\mathrm{}}=22-42\mathrm{}$ MeV. A striking resonance is observed at $E_{\mathrm{c}.\mathrm{m}.\mathrm{}}=30.75\mathrm{}$ MeV which correlates with a very pronounced structure in the ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$+${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ inelastic channels. The total resonance cross section observed in the ${}_{}{}^{10}{}_{}{}^{}\mathrm{B}$+${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$ channel implies a reduced partial width comparable to those of the inelastic channels. These data suggest, for the first time, the possible importance of nucleon degrees of freedom in the structure of the ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$+${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ resonances.
