Investigation of Nuclear Structure Using the Interacting Boson Model

* 9503095巴雷特 这个美洲计划奖将支持博士布鲁斯R。巴雷特，亚利桑那大学和阿卜杜拉耶·富拉·迪亚洛博士，巴拿马大学。 他们将使用相互作用玻色子模型（IBM）的1/A玻色子展开方法研究中到重质量核的核结构。 玻色子展开法是一种强有力的技术，用于研究大到无法处理的大质量核系统，即使在IBM的普通简化中也是如此。 这项研究将分两个阶段进行，使用1/a-boson展开方法的两个扩展。 这两个扩展将提供大量的应用程序的方法来研究现有的和新的测量结果在稀土和锕系元素的区域。在过去的二十年里，已经有越来越多的应用代数方法计算的核性质。 这种方法不仅突出了核行为的基本结构，而且有助于对周期表的整个区域进行系统研究。 Barrett博士在相互作用玻色子模型的应用、扩展和微观解释方面的经验补充了Diallo博士在1/A玻色子扩展方法方面的专业知识，后者帮助开发了该方法。 ***

*** 9503095 Barrett This Americas Program award will support a research collaboration between Dr. Bruce R. Barrett, University of Arizona, and Dr. Abdoulaye Foula Diallo, Universidad de Panama. They will investigate the nuclear structure of medium-to-heavy-mass nuclei using the 1/A-Boson-expansion method for the Interacting Boson Model (IBM). The Boson expansion method is a powerful technique for investigating massive nuclear systems too large to handle, even within the ordinary simplification of the IBM. The study will be done in two stages, using two extensions of the 1/a-boson expansion method. Both extensions will provide a large number of applications of the approach to the study of existing and newly measured results in the rare-earth and actinide regions.For the last two decades there has been an increased application of algebraic methods to the calculation of nuclear properties. Such an approach not only highlights the underlying structure of nuclear behavior, but also facilitates its systematic study over entire regions of the periodic table. Dr. Barrett experience regarding the application, extension and microscopic interpretation of the Interacting Boson Model complements Dr. Diallo's expertise on the 1/A-boson- expansion method which the latter helped to develop. ***
