Abstract

The reaction ${}^{12}C$ + ${}^{12}C$ has been studied at $E_{c . m .} = 2.5 to 6.2$ MeV by $γ$ -ray spectroscopy. New resonances were found below 4 MeV. When the influence of the Coulomb barrier is removed, these resonances are superimposed on a flat background, which does not show a strong increase at low energies, in contrast to previous work.
