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 8Lis 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.
