U.S.-China Cooperative Research (Physics): Studies of Nuclear Structure Physics

这是纽约州立大学石溪分校的大卫·福桑和布鲁克海文国家实验室的理查德·卡斯顿以及兰州兰州现代物理研究所的张敬业、中国共同完成的一个为期三年的合作项目。该项目由美国国家科学基金会和中国科学院联合发起。张教授是哥本哈根大学尼尔斯·玻尔研究所和橡树岭重离子联合研究所活跃在全球研究领域的领先核结构理论家。他与纽约州立大学石溪分校和布鲁克海文国家实验室的实验小组的访问将集中在三个研究领域，这三个领域涉及对实验计划的理论解释和指导。这三个研究领域是：(1)核形状，(2)核集体性来源，(3)动力学性质。第一个领域与特定的核子轨道对原子核形状的影响有关，第二个领域与中子的作用有关。质子相互作用在原子核中集体运动的开始，第三种是从涉及旋转运动的特定稳定区域到另一区域的跃迁。这个项目的关键是实验方法和理论方法之间的有效互动，以了解这些研究领域。

This is a three.year collaborative project between David Fossan of the State University of New York at Stony Brook and Richard Casten of Brookhaven National Laboratory and Zhang Jingye of the Lanzhou Institute of Modern Physics, Lanzhou, China. This project is sponsored jointly by NSF and the Chinese Academy of Sciences. Professor Zhang is a leading nuclear structure theorist active in worldwide research at the Niels Bohr Institute of the University of Copenhagen and the Joint Institute for Heavy Ion Research at Oak Ridge. His visits with the experimental groups at SUNY Stony Brook and Brookhaven National Laboratory will focus on three research areas that involve theoretical interpretation and guidance of the experimental programs. The three research areas are: (1) nuclear shapes, (2) the source of nuclear collectivity, and (3) dynamic properties. The first area relates to the influence that specific nucleon orbitals have on the shape of the nucleus, the second to the role of the neutron. proton interaction in the onset of collective motion in the nucleus, and the third to transitions from a specific region of stability involving rotational motion to another region. The key to this program is the effective interaction between the experimental and the theoretical approaches to the understanding of these research areas.
