U.S.-France Cooperative Research: Study of Exotic Nuclei with the Shell Model and the Interacting Boson Model

9415451 Barrett这一为期三年的奖项将支持亚利桑那大学的Bruce R.Barrett和法国卡昂GANIL(Grand Accelerateur National d‘Ions Lourds)的Piet van Isacker在核物理方面的美法合作研究。他们的研究目标是研究远离质子和中子线稳定线的奇异轻核的性质。为了研究所谓的“晕”结构，他们提出要达到高达A=11的质量。对大规模微观(也称为壳模型)计算的研究将得到利用相互作用玻色子模型-3的模型计算的补充。核结构理论和计算机技术的最新进展将应用于这些研究。巴雷特博士为这个项目带来了壳体模型计算和有效理论方面的专业知识。这与法国研究人员在群论和相互作用玻色子模型方面的经验是相辅相成的。该项目利用了GANIL的优良设施，包括一台非常强大的LISE光谱仪，并提供了与目前正在进行奇异轻核结构研究的实验小组的联系。这些关于原子核结构的研究在能源研究、物理和天文学中都有重要的应用。***

9415451 Barrett This three-year award will support U.S.-France cooperative research in nuclear physics between Bruce R. Barrett of the University of Arizona and Piet van Isacker at GANIL (Grand Accelerateur National d' Ions Lourds), Caen, France. The objective of their research is the study of properties of exotic light nuclei away from the proton and neutron lines of stability. They propose to reach as high a mass as A=11 in order to investigate the so-called "halo" structure. Studies on large-scale microscopic (also known as shell- model) calculations will be complemented by model calculations utilizing the Interactive Boson Model-3. Recent advances in nuclear structure theory and computer technology will be applied to these investigations. Dr. Barrett brings to this project expertise in shell-model calculations and effective theory. This is complemented by the French investigators' experience in group theory and Interacting Boson Model. The project takes advantage of excellent facilities at GANIL, including a very powerful LISE spectrometer, and provides access to an experimental group currently performing investigations on the structure of exotic light nuclei. These studies on nuclear structure have important applications in energy research, physics and astronomy. ***
