In this work, the elastic scattering of 6Li+[Formula: see text]Si system at wide range energies from 76 to 318[Formula: see text]MeV is analyzed. The analysis is carried out in the framework of the optical model (OM). Two different methods are adopted for nuclear optical potential of this system. The first method is the double folding cluster (DFC) for the real part supplied with an imaginary part in the Woods–Saxon (WS) form. In the second one, the double folding (DF) model based upon São Paulo potential (SPP) is used as real and imaginary parts each multiplied by a corresponding normalization factor. For [Formula: see text]Si, the full [Formula: see text]-cluster density is considered while the [Formula: see text]-deuteron ([Formula: see text]–[Formula: see text]) structure is considered for 6Li. Therefore, the DFC real central part is calculated by folding both [Formula: see text]–[Formula: see text] and [Formula: see text]–[Formula: see text] effective interaction between target and nuclei over the cluster densities of the target and projectile. The derived renormalized potentials give a successful description of the data. The present results are in good agreement with the previous work. This agreement confirms the validity of the present methods to generate nucleus–nucleus optical potentials.

6Li+28Si弹性散射的不同折叠模型

在这项工作中，弹性散射6Li+[公式：见正文]Si系统在76至318的宽能量范围内[公式：见正文]MeV进行了分析。分析是在光学模型（OM）的框架内进行的。该系统的核光学势采用两种不同的方法。第一种方法是实部的双折叠簇 (DFC)，并以 Woods-Saxon (WS) 形式提供虚部。在第二个中，基于圣保罗势 (SPP) 的双折叠 (DF) 模型用作实部和虚部，每个部分乘以相应的归一化因子。对于[公式：见文]Si，考虑完整的[公式：见文]-簇密度，而考虑[公式：见文]-氘核（[公式：见文]-[公式：见文]）结构为了6李。因此，DFC 实中心部分是通过将 [公式：见文本]-[公式：见文本] 和 [公式：见文本]-[公式：见文本] 在目标和弹丸。导出的重整化电位成功地描述了数据。目前的结果与之前的工作非常吻合。该协议证实了本方法产生核-核光学势的有效性。
