Abstract

The nuclear mean-field potential arising from the 12^{12}C+12^{12}C interaction at the low energies relevant for the astrophysical carbon burning process has been constructed within the double-folding model, using the realistic nuclear ground-state density of the 12^{12}C nucleus and the effective M3Y nucleon-nucleon (NN) interaction constructed from the G-matrix of the Paris (free) NN potential. To explore the nuclear medium effect, both the original density independent M3Y-Paris interaction and its density dependent CDM3Y6 version have been used in the folding model calculation of the 12^{12}C+12^{12}C potential. The folded potentials at the different energies were used in the optical model description of the elastic 12^{12}C+12^{12}C scattering at the energies around and below the Coulomb barrier, as well as in the barrier penetration model to estimate the fusion cross section and astrophysical SS factor of the 12^{12}C+12^{12}C reactions at the low energies. The obtained results are in good agreement with experimental data over a wide range of energies.
