项目摘要
Our knowledge of properties of neutron-rich nuclear matter, especially the density dependence of nuclear symmetry energy, is important for understanding many critical issues in nuclear physics, astrophysics and cosmology. The density and momentum dependence of the nucleon isovector potential is the most fundamental but currently very poorly known quantity determining properties of neutron-rich nuclear matter. Heavy-ion reactions, especially those induced by high energy radioactive beams, provide us the unique means to investigate properties of neutron-rich nuclear matter in terrestrial laboratories. In concert with the experimental efforts undertaken at several radioactive beam facilities in the US and abroad, I shall develop new theoretical tools to explore signatures of the density and momentum dependence of the isovector nucleon potential and the corresponding symmetry energy; continue to provide theoretical assistances in planning and data analyses of experiments; and evaluate timely astrophysical impact of the symmetry energy constrained by the latest terrestrial nuclear laboratory data.While carrying out the proposed work, I will carefully integrate my research and the education of students. Several undergraduate and graduate students will participate in carrying out the proposed work. I will emphasize and encourage early involvement of undergraduate students in research. This experience not only plays a vital role in their complete education but also provides a solid basis for them to become next generation scientists and engineers. Moreover, the continued NSF funding will also help significantly improve the environment and infrastructure for research, especially in nuclear physics and astrophysics, at Texas A&M University-Commerce.
丰中子核物质的性质,特别是核对称能的密度依赖性,对于理解核物理、天体物理和宇宙学中的许多关键问题具有重要意义。核子等矢势对密度和动量的依赖性是丰中子核物质最基本但目前知之甚少的决定性质的量。重离子反应,特别是高能放射性束引起的重离子反应,为我们在地面实验室研究丰中子核物质的性质提供了独特的手段。在与美国和国外几个放射性束流设施进行的实验工作相一致的情况下,我将开发新的理论工具来探索等矢量核子势和相应对称能的密度和动量依赖性的特征;继续为实验的计划和数据分析提供理论帮助;并及时评估最新地球核实验室数据约束下的对称能对天体物理的影响。在开展拟议工作的同时,我将认真结合我的研究和学生的教育。一些本科生和研究生将参与开展拟议的工作。我将强调并鼓励本科生尽早参与研究。这些经验不仅在他们的完整教育中发挥着至关重要的作用,而且为他们成为下一代科学家和工程师提供了坚实的基础。此外,持续的NSF资助也将有助于显着改善环境和基础设施的研究,特别是在核物理和天体物理学,在得克萨斯州农工大学商业。
