The fusion excitation functions for the reaction of 9Li with 70Zn and 208Pb were measured. In the reaction with 70Zn, the evaporation residues (EVRs) were detected by a radiochemical separation of the As and Ge EVRs followed by β-counting. In the reaction with 208Pb, the At EVRs were detected by α-counting. In both systems, one observes substantial sub-barrier fusion enhancement that cannot be explained by coupled channels calculations. The implication of these studies for the study of the 11Li + 208Pb reaction are discussed.
