Heavy-ion fusion reactions between light nuclei such as carbon and oxygen isotopes have been studied because of their significance for a wide variety of stellar burning scenarios. One important stellar reaction is 12C+12C, but it is difficult to measure it in the Gamow window because of very low cross sections and several resonances occurring. Hints can be obtained from the study of 13C+12C reaction. We have measured it by an activation method for energies down to Ecm=2.5 MeV using 13C beams from the Bucharest 3 MV tandetron and gamma-ray deactivation measurements from the resulting 24Na, in our low and ultra-low background laboratories. The latter is located in a salt mine about 100 km north of Bucharest. Results of the experiments so far are shown and discussed in connection with the possibility to go even further down in energy and with the interpretation of the reaction mechanism at such deep sub-barrier energies. Possibilities to further use the combination high current tandetron accelerator and ultra-low background salt mine laboratory for nuclear astrophysics are also assessed.
