We present a simultaneous analysis of the elastic scattering and fusion cross-section data of the C-12 + Mg-24 system around the Coulomb barrier and over energies by using the microscopic alpha-alpha double folding cluster potential within the framework of the optical model and the coupled-channels formalism. The alpha-alpha double folding cluster potential is obtained by using the alpha-cluster distribution densities of the nuclei in the usual double folding procedure. The microscopic potential results are compared with the findings of the phenomenological deep and shallow potentials. It is subsequently shown that only phenomenological deep, real, microscopic nucleon-nucleon and alpha-alpha double folding cluster potentials provide a consistent description of the angular distributions and fusion cross-section data simultaneously. The effect of the inclusion of the excited states of the target nucleus Mg-24 on the fusion cross-section predictions is also determined by the coupled-channels calculations, which are shown to improve the agreement.
