Abstract

The energy dependence of the reation ${}^{12}C$ ( ${}^{12}C$ , ${}^{10}B$ ) ${}^{14}N$ has been studied in the range $E_{c . m .} = 22 - 42$ MeV. A striking resonance is observed at $E_{c . m .} = 30.75$ MeV which correlates with a very pronounced structure in the ${}^{12}C$ + ${}^{12}C$ inelastic channels. The total resonance cross section observed in the ${}^{10}B$ + ${}^{14}N$ 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 ${}^{12}C$ + ${}^{12}C$ resonances.
