Towards a unified description of evaporation- residue fusion cross-sections above the barrier
A meticulous study of nearly 300 fusion- evaporation cross-section data reveals that, when properly scaled, fusion excitation function complies with a universal homographic law which is, within experimental errors, reaction system independent. From such complete and summed complete and incomplete fusion excitation functions are extracted the limiting energy for the complete fusion and the main characteristics (onset, maximum and vanishing) of the incomplete fusion. The DYWAN microscopic transport model correctly predicts the incomplete fusion cross- section for incident energies greater than or similar to 15A MeV and suggests that the nuclear transparency is at the origin of fusion disappearance.
