*** 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. ***

*** 9503095 Barrett这项美洲计划奖将支持亚利桑那大学Bruce R. Barrett博士和巴拿马大学的Abdoulaye Foula Diallo博士之间的研究合作。 他们将使用相互作用的玻色子模型（IBM）的1/a-boson扩张法（IBM）研究中至重型质量核的核结构。 玻色子扩展方法是一种强大的技术，即使在IBM的普通简化中，也可以调查太大而无法处理的大规模核系统。 该研究将使用1/A-boson扩展方法的两个扩展分为两个阶段进行。 这两种扩展都将在稀土和actinide区域的现有和新测量结果的研究中提供大量应用。在过去的二十年中，代数方法在计算核特性中的应用增加了。 这种方法不仅突出了核行为的潜在结构，而且还促进了其在周期表的整个区域的系统研究。 Barrett博士在相互作用的玻色子模型的应用，扩展和显微镜解释方面的经验补充了Diallo博士在后者有助于开发的1/A-Boson扩展方法方面的专业知识。 ***
