Abstract

Excitation functions for sub- and near-barrier total (complete + incomplete) fusion cross sections are presented for the [Formula Presented] reactions. Evaporation residues were identified by their characteristic [Formula Presented] rays and the corresponding yields measured with both the IReS Garel [Formula Presented] array at the Vivitron facility and with the São Paulo Ge array at the 8UD Pelletron tandem facility using standard γ-ray techniques. The data extend to medium-mass systems previous works exploring the coupling effects (hindrance versus enhancement) in fusion reactions of both lighter and heavier systems. The results indicate a small enhancement of total fusion for the more weakly bound [Formula Presented] at sub-barrier energies, with similar cross sections for both reactions at and above the barrier.
