We present a comprehensive coupled reaction channels analysis of the C+Pb system over a broad range of bombarding energies, employing the parameter-free São Paulo potential for the real part of the nuclear interaction. The calculations include couplings to low-lying inelastic states and transfer channels, with no adjustable parameters. Theoretical results are compared with experimental data for elastic scattering, fusion, inelastic excitation, and transfer cross sections. The inclusion of channel couplings significantly improves the agreement with the data. These findings reaffirm the predictive power of the São Paulo potential and underscore the importance of coupled reaction channels calculations in describing heavy-ion collisions, not only near the Coulomb barrier but also at much higher energies.
