Coincidence measurements of breakup fragments in reactions of ${^{6, 7}{\rm{Li}}}$ with ${^{209}{\rm{Bi}}}$ 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 ( $\alpha + t$, $\alpha + d$, $\alpha + p$, and $\alpha + \alpha$) are distinguished. A new breakup mode, $\alpha + t$, is observed in ${^{6}{\rm{Li}}}$-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.

6,7Li 与 209Bi 在库仑势垒附近及以上能量反应中断裂通道的相对概率 国家自然科学基金 (11635015, U1832130, 11975040), 软件开发环境国家重点实验室 (SKLSDE-2020ZX-16) )、持续基础科学研究项目(WDJC-2019-13)和领先创新项目(LC192209000701、LC202309000201)

在反应解体片段符合测量的${^{6, 7}{\rm{Li}}}$${^{209}{\rm{Bi}}}$在约能量和库仑势垒上面进行了使用大立体角覆盖检测器阵列。通过Q与解体片段的相对能量,不同的解体组分(提示分手和延迟分手)和不同的破裂模式沿值($\alpha + t$$\alpha + d$$\alpha + p$,和$\alpha + \alpha$)来区分。$\alpha + t$观察到一种新的分裂模式${^{6}{\rm{Li}}}$- 能量高于库仑势垒的诱导反应。研究了破裂模式和破裂分量之间的相关性以及它们与入射能量的变化。结果将帮助我们更好地理解弱束缚核对抑制完全聚变的分裂效应,特别是对于高于势垒的能量。
