摘要

我们利用半微观势重新分析了11-30 MeV范围内6,7,8 li + 9Be散射的弹性角分布（ADs）。本研究探讨了弱束缚（WB）弹丸如何影响弹性散射，重点是破裂效应和同位素依赖性。通过对双折叠电位（SPP, BDM3Y1， CDM3Y1和CDM3Y6）的系统测试，我们发现了不同的行为：6Li由于其低结合能（1.47 MeV）而表现出增强的分裂，而8Li的中子晕结构促进了转移通道。在库仑势垒附近持续存在的假想电位证实了破裂阈值异常（BTA）。这些结果提高了我们对核反应动力学的理解，并对涉及轻核的天体物理过程具有启示意义。

Breakup and isotopic effects in the scattering of 6,7,8Li projectiles from a 9Be target

We reanalyze elastic angular distributions (ADs) for ^6,7,8Li + ⁹Be scattering in the 11–30 MeV energy range using semi-microscopic potentials. This study examines how weakly bound (WB) projectiles affect elastic scattering, focusing on breakup effects and isotopic dependencies. Through systematic tests of double-folding potentials (SPP, BDM3Y1, CDM3Y1, and CDM3Y6), we identify distinct behaviors: ⁶Li shows enhanced breakup due to its low binding energy (1.47 MeV), whereas ⁸Li’s neutron-halo structure promotes transfer channels. The persistent imaginary potential near the Coulomb barrier confirms the breakup threshold anomaly (BTA). These results improve our understanding of nuclear reaction dynamics and have implications for astrophysical processes involving light nuclei.
