Consistent analysis of fusion data without adjustable parameters for a wide variety of heavy-ion systems

We have calculated fusion cross sections for 64 heavy-ion systems based on a method that takes into account the couplings to a complete set of states for surface vibrations of the nuclear densities. For the nuclear interaction we have assumed the parameter-free São Paulo potential. The predictions have been obtained without using any adjustable parameter, and are in good agreement with the experimental results for most of the systems, even at sub-barrier energies.
