Fusion calculations for ⁴⁰Ca+⁴⁰Ca, ⁴⁸Ca+⁴⁸Ca, ⁴⁰Ca+⁴⁸Ca and p+²⁰⁸Pb systems

The fusion cross sections of calcium isotopes and proton induced fusion have been calculated in terms of a coupled-channels formulation. Results indicated that there are big differences between the two fusion types. In the calculations of calcium isotopes fusion, the pair-transfer coupling has been applied in addition to the vibrational coupling, the combined effects showed that pair-transfer has played a significant role in the fusion process for the asymmetric ⁴⁰Ca+⁴⁸Ca system. The result of proton induced fusion for p+²⁰⁸Pb system successfully presents the fusion oscillation, which agrees with the experimental data rather well
