The12C+12C reaction at subcoulomb energies (I)

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

The reaction12C+12C has been studied in the energy rangeE cm=2.45–6.15 MeV byγ-ray spectroscopy. Gamma-ray transitions from a large number of excited states in20Ne,23Na and23Mg were observed, which show strong and rapid yield variations. When the influence of the Coulomb barrier is removed, these structures appear superimposed on a flat reaction yield, which does not show a strong increase at low energies, in contrast to previous work. These results obviate the need for the hypothesis of absorption under the barrier at least down toE cm=2.45 MeV. The nuclear and astrophysical aspects of the data are discussed.
