Abstract

We test microscopic global optical potential in three-body calculations of deuteron–nucleus scattering. We solve Faddeev-type equations for three-body transition operators. We calculate differential cross section and analyzing power for the deuteron elastic scattering and breakup in collisions with \({}^{12}\)C, \({}^{16}\)O and \({}^{24}\)Mg nuclei, and find a reasonable agreement with available experimental data. Comparison with respective predictions using phenomenological optical potentials reveals systematic deviations in particular kinematic regimes.

利用微观全局光学势能进行氘核散射的三体计算

我们测试了氘核散射三体计算中的微观全局光学势。我们求解了三体转换算子的法德夫型方程。我们计算了氘核在与\({}^{12}\)C、\({}^{16}\)O 和\({}^{24}\)Mg 核碰撞时的弹性散射和破裂的微分截面和分析功率，发现与现有实验数据有合理的一致性。通过与使用现象学光学势的各自预测进行比较，发现在特定运动状态下存在系统性偏差。

期刊介绍： The journal Few-Body Systems presents original research work – experimental, theoretical and computational – investigating the behavior of any classical or quantum system consisting of a small number of well-defined constituent structures. The focus is on the research methods, properties, and results characteristic of few-body systems. Examples of few-body systems range from few-quark states, light nuclear and hadronic systems; few-electron atomic systems and small molecules; and specific systems in condensed matter and surface physics (such as quantum dots and highly correlated trapped systems), up to and including large-scale celestial structures. Systems for which an equivalent one-body description is available or can be designed, and large systems for which specific many-body methods are needed are outside the scope of the journal. The journal is devoted to the publication of all aspects of few-body systems research and applications. While concentrating on few-body systems well-suited to rigorous solutions, the journal also encourages interdisciplinary contributions that foster common approaches and insights, introduce and benchmark the use of novel tools (e.g. machine learning) and develop relevant applications (e.g. few-body aspects in quantum technologies).
