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.

该奖项将支持亚利桑那大学布鲁斯·巴雷特博士和墨尔本大学伊恩·莫里森博士之间的合作研究。 该提案旨在研究和比较核结构模型。 特别是，该研究的目的是将模型（相互作用玻色子模型）扩展到较轻质量的核，并在模型中进行适当的添加和/或更改，该模型已被证明可以成功地描述较高质量核的结构和性质。 该项目代表了澳大利亚小组之间的出色合作，该小组一直是使用膨胀技术通过相互作用玻色子模型进行计算的领导者，并且巴雷特对几个核结构模型进行了严格评估。 这是一项重要的基础工作，有可能开发出轻到中到重质量核的统一图像。
