| 英文摘要 | The reaction cross section of the C-12+C-12 system is difficult to measure because of the presence of the resonances in the Gamow energy window. It has been proved that the C-13+C-12 reaction is a good alternative to study the behavior of the reaction cross section at energies relevant for astrophysics. We have measured it with activation and online techniques. During online measurements we were interested to determine the relative contributions of the open channels of the C-13+C-12 reaction. These determinations are necessary to evaluate the total fusion reaction cross section. Therefore, we have measured the gamma-ray yields of proton, neutron and alpha particle evaporation channels from the resulting Mg-25 compound nucleus using prompt gamma-rays measurements. This complements the activation method. The irradiations took place at the 3 MV Tandetron Accelerator at IFIN-HH [1], Bucharest and the prompt gamma-rays were measured using a hyper-pure germanium detector with 100% relative efficiency, shielded with lead bricks. The energy range for the irradiation was from 4.6 up to 11 MeV (in laboratory frame), in steps of 0.2 MeV and the online measurements were performed from 6.4 up to 11 MeV. |
