ResumoExcitation functions for sub- and near-barrier total (complete + incomplete) fusion cross sections are presented for the 6,7Li+59Co reactions. Evaporation residues were identified by their characteristic γ rays and the corresponding yields measured with both the IReS Garel + 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 6Li at sub-barrier energies, with similar cross sections for both reactions at and above the barrier.Received 24 February 2003DOI:https://doi.org/10.1103/PhysRevC.67.054602©2003 American Physical Society
