Nuclear Structure and Nuclear Astrophysics

密歇根州立大学提出了一项为期三年的拨款，支持一个核理论教师小组的研究，B. a . Brown教授和V. Zelevinsky教授以及M. Horoi（中密歇根大学）。提出的研究涵盖了核结构和核天体物理学的广泛主题，对国家超导回旋实验室正在进行的项目很重要。主要成分是原子核的结构性质，包括那些远不稳定的性质，以及它们在核反应和天体物理现象中的表现。该小组的丰富经验，以及来自msuu和NSCL的支持提供了。一个多样化和专题研究计划的基础。所提出的研究是现代核物理学的主流，旨在回答一些主要问题：什么是核稳定性的极限，宇宙的化学进化是如何进行的，相互作用的多体系统的自组织方式是什么，有序如何与混沌和复杂性共存。所提出的研究的具体方向在逻辑上遵循小组以前的经验。建议的主要主题是(i)发展新的分析和计算工具，用于描述核结构和核反应，特别是远离稳定的核；详细考虑具体的核现象和核过程，这些现象和核过程揭示了在进入不稳定核的处女地时所遇到的新特征；（iii）对天体物理学有兴趣的核过程的结构和动力学方面的计算和建模；（四）多体量子混沌及其在核结构和核反应中具有集体性和规律性特征的共存研究。建议的计划预计会对香港的发展产生可观的影响。核理论和核天体物理学领域。它也会。改变实验电子竞技的方向。在更广泛的背景下，该计划的成功进展对我们理解宇宙中物质和核合成的基本成分非常重要。核结构中的多体性质、混沌和集体性的研究具有很强的跨学科性，因为原子核是自我维持的典型例子。具有强相互作用的非费米系统。历史上有很多想法。在核理论背景下形成的RST为物理学的其他分支提供了养分。这项提议的研究有望帮助研究玻色和费米凝聚物、复杂分子、固态微器件和量子计算的物理学。该提案具有相当大的教育成分，是NSCL/MSU高排名核物理项目的一部分。

Michigan State University proposes a three-year grant supporting the researchof a faculty group in nuclear theory, Professors B. A. Brown and V. Zelevinsky,together with M. Horoi (Central Michigan University). The research proposedencompasses a broad range of topics in nuclear structure and nuclear astrophysicsimportant for the ongoing program at the National Superconducting CyclotronLaboratory. The main components are structural properties of nuclei, includingthose far from stability, and their manifestation in nuclear reactions and astrophysicalphenomena. The rich experience of the group and the support from MSUand NSCL provides the .rm basis for a diverse and topical research program.The proposed research is in the mainstream of modern nuclear physics that isdirected to answering principal questions what are the limits of stability of nuclei,how did the chemical evolution of the Universe proceed, what are theways of self-organization in interacting many-body systems - how does order coexistwith chaos and complexity. Concrete directions of the proposed researchlogically follow from the previous experience of the group. Suggested main topicsare (i) development of new analytical and computational tools for the descriptionof nuclear structure and nuclear reactions, especially for the nuclei far fromstability; (ii) detailed consideration of speci.c nuclear phenomena and nuclearprocesses that shed light on the new features encountered with the advances intovirgin territory of unstable nuclei; (iii) calculations and modeling of structuraland dynamical aspects of nuclear processes of astrophysical interest; (iv) studiesof many-body quantum chaos and its coexistence with collective and regularfeatures in nuclear structure and reactions.The suggested program is expected to have appreciable impact on the developmentin the .eld of nuclear theory and nuclear astrophysics. It will also in.uencethe direction of the experimental e.orts. In a broader context, successful progressin the program is important for our understanding of the basic constituents ofmatter and nucleosynthesis in the Universe. The studies of many-body properties,chaos and collectivity in nuclear structure, have a strong interdisciplinaryaspect since the nucleus is an exemplary case of a self-sustaining .nite Fermisystemwith strong interactions. Historically, many ideas .rst formulated in thecontext of nuclear theory fertilized other branches of physics. The proposed researchis expected to help studies in physics of Bose- and Fermi-condensates,complex molecules, solid state microdevices and quantum computing. The proposalhas a considerable educational component being part of the highly rankednuclear physics program at NSCL/MSU.
