Excitation Functions of the ReactionC12+C13

Excitation functions have been measured for the $\alpha$-particle, proton, and elastic channels of the reaction ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ + ${}_{}{}^{13}{}_{}{}^{}\mathrm{C}$ at several angles in the energy range $E_{\mathrm{lab}}=16-28\mathrm{}$ MeV. Observed structures cannot be due to molecular-type doorway states as is the case for the sub-Coulomb resonances of the reaction ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ + ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$.
