Abstract
We have measured the fusion excitation function for the reaction for near-barrier projectile center-of-mass energies of to MeV using the ISAC2 facility at TRIUMF. The -emitting evaporation residues () were stopped in the target, and their decay was measured. The isotopic yields at each energy were in good agreement with the predictions of a statistical model code (HIVAP). The measured fusion excitation function shows evidence for substantial sub-barrier fusion enhancement not predicted by current theoretical models. There is a suppression of the above barrier cross sections relative to these model predictions. The implications of this measurement for studying the fusion of with are discussed.
