Unified calculations of scattering and fusion reactions on the systems 28Si + 58Ni and 28Si + 64Ni at near-Coulomb barrier energies

Fusion cross-section, elastic and 21+-inelastic scattering cross-sections for the systems 28Si + 58Ni and 28Si + 64Ni are calculated at several energies around the Coulomb barrier energies by using a unified coupled-channel approach. The calculations of the scattering and fusion cross-sections are done simultaneously with a single set of optical potential parameters obtained from a χ2-analysis of the elastic and fusion data. The excitation channels 21+, 31- and 2-neutron transfer are included explicitly in the total wave function of the nuclear system. A comparison of the results is made to corresponding experimental data
