| Abstract: | The 13C+13C total fusion cross section has been determined in the range 3.26⩽Ec.m.⩽8.0 MeV using Ge(Li) detector measurements of low-lying transitions in the residual nuclei and a statistical model calculation of excited state populations. The six most abundantly produced residual nuclei have been observed and their yields are given. To constrain the parameters in fusion models for these reactions, we have also taken elastic scattering data at θc.m.=60°, 70°, 80°, and 90° for 4.5⩽Ec.m.⩽8.5 MeV, as well as angular distributions at Ec.m.=7.0 and 8.0 MeV. The IWBC model and an optical model with a “shallow” potential have been used for parametrizing the nucleus-nucleus interaction. |
