U.S.-Australia Cooperative Research: Nuclear Structure Theory: Investigations of Collective Models

该奖项将支持亚利桑那大学的布鲁斯·巴雷特博士和墨尔本大学的伊恩·莫里森博士之间的合作研究。这项建议是为了调查和比较核结构模型。特别是，这项研究的目的是将相互作用玻色子模型--已被证明成功地描述较高质量核的结构和性质的模型--扩展到较轻质量的核，并对该模型进行适当的添加和/或改变。该项目代表了澳大利亚小组在使用扩展技术进行相互作用玻色子模型计算方面的领先者与巴雷特对几个核结构模型的关键评估之间的出色合作。这是一项重要的基础性工作，有可能形成轻、中、重质量原子核的统一图景。

This award will support collaborative research between Dr. Bruce Barrett of the University of Arizona and Dr. Iain Morrison of the University of Melbourne. This proposal is to investigate and compare nuclear structure models. In particular, the objective of the research is to extend a model, the Interacting Boson Model, which has proven successful in describing the structure and properties of higher-weight nuclei, to lighter-mass nuclei, with appropriate additions and/or changes in the model. The project represents excellent collaboration between the Australian group who have been leaders in the use of expansion techniques for performing calculations with the Interacting Boson Model and Barrett's critical assessment of several nuclear structure models. This is important fundamental work with the potential to develop a unified picture of light to medium-to-heavy mass nuclei.
