In the context of the double folding optical model, the strong refractive effect for elastic scattering of ¹¹Li + ¹²C and ¹¹Li + ²⁸Si systems at incident energies of 29, 50, and 60 MeV/n is studied. Real folded potentials are generated based on a variety of nucleon-nucleon interactions with the suggested density distributions for the halo structure of ¹¹Li nuclei. The rearrangement term (RT) of the extended realistic density dependent CDM3Y6 effective interaction is considered. The imaginary potential was taken in the traditional standard Woods-Saxon form. Satisfactory results for the calculated potentials are obtained, with a slight effect of the RT in CDM3Y6 potential. Successful reproduction with a normalization factor close to one for the observed angular distributions of the elastic scattering differential cross section has been achieved using the derived potentials. The obtained reaction cross-section is studied as a guide by extrapolating our calculations and previous results.

在双折叠光学模型的背景下，研究了¹¹ Li + ¹² C和¹¹ Li + ²⁸ Si系统在入射能量29、50和60 MeV / n下的弹性散射的强折射效应。实际的折叠势是基于各种核子-核子相互作用以及¹¹的晕结构的建议密度分布而产生的锂核。考虑了扩展的现实密度相关的CDM3Y6有效相互作用的重排项（RT）。虚构的潜力采用传统的标准Woods-Saxon形式。获得了令人满意的计算电位结果，而RT对CDM3Y6电位的影响很小。使用导出的电势已经成功实现了对弹性散射微分横截面的角度分布观察到的归一化因子接近于1的成功复制。通过推断我们的计算结果和先前的结果，对获得的反应截面进行了研究。
