Abstract

The experimental angular distribution data for the deuteron\(+\) ²⁴Mg elastic scattering system at energies between 8.65 and 170 MeV were re-analysed using the nuclear optical model. Three types of real optical potentials are considered: phenomenological Woods–Saxon, microscopic folding based on effective nucleon–nucleon interactions (CDM3Y6 and JLM) and cluster-folded potentials. A combination of volume and surface imaginary potentials is important for accurately describing the experimental data. A surface contribution to the real potential simulates the dynamical polarisation potential caused by deuteron breakup, improving agreement with the measured cross-sections without needing coupled-channel calculations. The energy dependence of potential parameters, along with other calculated quantities, is also examined. Both the phenomenological and the re-normalised cluster-folded potentials show good agreement with the experimental results, with the latter aligning well with the standard re-normalised folding potential in previous studies.

氘核+ 24Mg弹性散射的不同折叠势分析

利用核光学模型重新分析了能量在8.65 ～ 170 MeV之间的氘核\(+\) 24Mg弹性散射系统的实验角分布数据。考虑了三种类型的真实光学势：现象学的Woods-Saxon，基于有效核子-核子相互作用的微观折叠（CDM3Y6和JLM）和团簇折叠势。体积虚电位和表面虚电位的结合对于准确描述实验数据是很重要的。实际势的表面贡献模拟了氘核分裂引起的动态极化势，提高了与测量截面的一致性，而无需耦合通道计算。势能参数的能量依赖性，以及其他计算量，也进行了检查。现象电位和再归一化团簇折叠电位与实验结果吻合较好，其中再归一化团簇折叠电位与前人研究的标准再归一化团簇折叠电位吻合较好。
