Recently, Zevallos et al [Phys. Rev. C99, 064613 (2019)] measured, for the first time, the elastic scattering data of $$^{12}\hbox {B}+{}^{58}\hbox {Ni}$$ reaction at $$E_{\text {Lab}} = 30.0$$ and 33.0 MeV. For the first time, we show a comprehensive theoretical analysis of the experimental data of $$^{12}\hbox {B}+{}^{58}\hbox {Ni}$$ reaction. First, we propose alternative density distributions for the $$^{12}\hbox {B}$$ nucleus, and obtain the elastic scattering angular distributions of $$^{12}\hbox {B} +{}^{58}\hbox {Ni}$$ reaction with the help of these densities. Secondly, we calculate the elastic scattering cross-sections of $$^{12}\hbox {B} + {}^{58}\hbox {Ni}$$ reaction by using 13 different nuclear potentials to reveal alternative nuclear potentials. Finally, we examine cluster structures such as $$\alpha +{}^{8}\hbox {Li}$$ and $$n+{}^{11}\hbox {B}$$ of the $$^{12}\hbox {B}$$ nucleus by using a simple approach, and acquire elastic scattering cross-sections of $$^{12}\hbox {B}+{}^{58}\hbox {Ni}$$ reaction over these cluster approaches. We compare all the theoretical results with the experimental data, and discuss their similarities and differences. Also, we propose new equations of both normalisation constant and imaginary potential parameters for all the systems analysed.

$$^{12}\hbox {B}+{}^{58}\hbox {Ni}$$ 弹性散射的综合理论分析首次使用不同密度分布、不同核势和不同聚类方法测量

最近，Zevallos 等 [Phys. Rev. C99, 064613 (2019)] 首次测量了$$^{12}\hbox {B}+{}^{58}\hbox {Ni}$$在$$反应的弹性散射数据E_{\text {Lab}} = 30.0$$ 和 33.0 MeV。我们首次对$$^{12}\hbox {B}+{}^{58}\hbox {Ni}$$反应的实验数据进行了全面的理论分析。首先，我们为 $$^{12}\hbox {B}$$ 核提出替代密度分布，并获得 $$^{12}\hbox {B} +{}^{58} 的弹性散射角分布\hbox {Ni}$$ 在这些密度的帮助下反应。其次，我们通过使用 13 种不同的核势来揭示替代核势，计算 $$^{12}\hbox {B} + {}^{58}\hbox {Ni}$$ 反应的弹性散射截面。最后，我们检查 $$\alpha +{}^{8}\hbox {Li}$$ 和 $$n+{}^{11}\hbox {B}$$ 的簇结构，例如 $$^{12}\ hbox {B}$$ 核通过使用简单的方法获得 $$^{12}\hbox {B}+{}^{58}\hbox {Ni}$$ 反应在这些簇上的弹性散射截面方法。我们将所有理论结果与实验数据进行比较，并讨论它们的异同。此外，我们为所有分析的系统提出了归一化常数和虚势参数的新方程。
