US-Mexico Cooperative Research: Microscopic Study of Collection Phenomena in Deformed Nuclei

该奖项将支持路易斯安那州立大学的J.P.Draayer教授与墨西哥墨西哥城国立大学(UNAM)的O.Castanos教授合作。这项研究的目的是发展一幅表征原子核的集体模式的微观图景。研究人员打算：1)发展势能表面现象学集体模型的壳模型理论；2)研究李代数的膨胀和收缩机制，以及如何利用它们来更好地理解原子核所表现的微观-宏观二元性；3)强变形奇A核的多粒子理论的发展，即重现Nilsson模型现象学的壳模型理论。研究人员以前有过成功合作的历史。这项联合工作结合了墨西哥理论物理研究小组的优势和路易斯安那州立大学在使用群体方法应用于物理有趣(实验)现象方面的专业知识。这项计划中的研究应该有助于支持美国从事理论低能核结构工作的相对较少的小组之一。

This award will support Prof. J. P. Draayer of Louisiana State University in collaboration with Prof. O. Castanos of the Universidad Nacional de Mexico (UNAM) in Mexico City, Mexico. The objective of the research is to develop a microscopic picture of collective modes that characterize nuclei. The researchers intend to pursue: 1) the development of a shell-model theory for a collective model of potential energy surface phenomenology; 2) a study of the expansion and contraction mechanisms of Lie algebras and how they can be used to gain a better understanding of the microscopic-macroscopic duality that nuclei display; and 3) the development of a many-particle theory of strongly deformed odd-A nuclei, that is, a shell-model theory that reproduces Nilsson model phenomenology and perhaps more. The researchers have had a previous history of successful collaboration. This joint effort combines the strengths of the Mexican research group in theoretical physics with the LSU expertise in the use of group methods in applications to physically interesting (experimental) phenomena. The planned research should help to bolster one to the relatively few groups in the U.S. doing theoretical low-energy nuclear structure work.
