摘要:

我们回顾了近期进展,并论证了在核光学势方面进一步发展的必要性,这些光学势广泛用于核子弹性散射和反应截面的理论分析。在核素图中远离稳定线的区域,这代表了未来十年核科学的前沿,并将在全球新建的稀有同位素束设施中进行探测,目前有针对性的需求是量化和减少理论反应模型的不确定性,特别是关于核光学势的不确定性。我们首先描述了改进涉及短寿命同位素核反应描述的主要物理动机,重点阐述其对基础科学发现的益处以及在医学、能源和安全领域的应用。随后,我们概述了当前用于构建光学势的各种方法,从唯象学、微观到从头算方法,并特别强调了每种方法的优缺点。接着,我们讨论了公开可用的工具和资源,这些工具和资源有助于将该领域的最新进展传播给实践者。最后,我们提出了一系列开放挑战和建议,以推动该领域在稀有同位素束时代实现核反应研究的基础科学目标。

英文摘要:

We review recent progress and motivate the need for further developments in nuclear optical potentials that are widely used in the theoretical analysis of nucleon elastic scattering and reaction cross sections. In regions of the nuclear chart away from stability, which represent a frontier in nuclear science over the coming decade and which will be probed at new rare-isotope beam facilities worldwide, there is a targeted need to quantify and reduce theoretical reaction model uncertainties, especially with respect to nuclear optical potentials. We first describe the primary physics motivations for an improved description of nuclear reactions involving short-lived isotopes, focusing on its benefits for fundamental science discoveries and applications to medicine, energy, and security. We then outline the various methods in use today to build optical potentials starting from phenomenological, microscopic, and ab initio methods, highlighting in particular the strengths and weaknesses of each approach. We then discuss publicly-available tools and resources facilitating the propagation of recent progresses in the field to practitioners. Finally, we provide a set of open challenges and recommendations for the field to advance the fundamental science goals of nuclear reaction studies in the rare-isotope beam era.
