摘要

Coincidence measurements of breakup fragments in reactions of 6,7Li with 209Bi at energies around and above the Coulomb barrier were carried out using a large solid-angle covered detector array.Through the Q values along with the relative energies of the breakup fragments,different breakup components (prompt breakups and delayed breakups) and different breakup modes (α + t,α + d,α + p,and α + α) are distinguished.A new breakup mode,α+t,is observed in 6Li-induced reactions at energies above the Coulomb barrier.Correlations between breakup modes and breakup components as well as their variations with the incident energy are investigated.The results will help us better understand the breakup effects of weakly bound nuclei on the suppression of a complete fusion,particularly for the above-barrier energies.
