Nuclear Structure and Nuclear Astrophysics

密歇根州立大学提出了一项为期三年的资助计划，以支持一个核理论教师团体的研究，B教授。A. Brown和V. Zelevinsky，以及M. Horoi（Central Michigan University）.这项研究涵盖了核结构和核天体物理学领域的广泛主题，对于国家超导回旋加速器实验室正在进行的项目非常重要。主要内容是原子核的结构性质，包括那些远离稳定性的性质，以及它们在核反应和天体物理现象中的表现。该小组的丰富经验和来自MSU和NSCL的支持为多样化和专题研究计划提供了.rm基础。拟议的研究是现代核物理学的主流，旨在回答核稳定性的极限是什么，宇宙的化学演化是如何进行的，在相互作用的多体系统中，自组织的方式是什么？秩序如何与混乱和复杂性共存？ 具体的方向，拟议的研究逻辑遵循从以前的经验，该集团。建议的主要课题是：（i）发展新的分析和计算工具，用于解释核结构和核反应，特别是远离稳定核的结构和反应;（ii）详细研究特殊的核现象和核过程，揭示不稳定核领域的新进展所遇到的新特征;具有天体物理学意义的核过程的结构和动力学方面的计算和建模;（iv）对多项─体量子混沌及其与原子核结构和反应中集体性和规则性的共存，所提出的方案可望产生可观的影响关于核理论和核天体物理学领域的发展。这对今后的实验研究也有一定的指导意义。在更广泛的背景下，该计划的成功进展对于我们理解宇宙中物质和核合成的基本组成非常重要。由于原子核是强相互作用的自维持费米系统的典型例子，因此对原子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质。从历史上看，许多最初在原子核理论中形成的思想，丰富了物理学的其他分支。这项研究将有助于玻色和费米凝聚体、复杂分子、固态微器件和量子计算的物理研究。该提案有相当大的教育组成部分是高度rankednuclear物理程序在NSCL/MSU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.
