U.S.-Korea Cooperative Research on Multipole Matrix Element Zeroes in Resonances in Independent Particle Approximation

该提案要求提供资金，允许匹兹堡大学物理天文学系詹姆斯·e·贝菲尔德博士和理查德·h·普拉特博士与韩国首尔淑明女子大学物理系吴成达博士进行为期24个月的研究。独立粒子近似共振中多极矩阵元零的协同理论研究程序。具体来说，该项目将处理“库珀极小值”和形状共振的理论研究，这两个主要特征将筛选原子中的辐射跃迁与简单的点库仑氢情况区分开来。该项目涉及两组具有互补技能和设施的研究人员的合作研究。主要合作者是备受尊敬的科学家，他们多年来一直在研究领域合作。他们的合作非常成功，并在评审期刊上发表了几篇联合出版物。提出的多极矩阵元素零点和共振的研究将揭示电子屏蔽情况下简单点库仑行为的偏差。该项目与美韩合作科学项目的目标相关，该项目旨在通过科学信息、思想、技能和技术的交流以及在互利问题上的合作，提高美韩科学家和工程师之间的合作水平。

This proposal requests funds to permit Dr. James E. Bayfield and Dr. Richard H. Pratt, Department of Physics and Astronomy, University of Pittsburgh, to pursue with Dr. Sung Dahm Oh, Department of Physics, Sookmyung Women's University, Seoul, Korea, for a period of 24 months, a program of cooperative theoretical research on multipole matrix element zeroes in resonances in independent particle approximation. Specifically, the project will deal with theoretical investigations of "Cooper Minima" and shape resonances, two main features which distinguish radiation transitions in a screened atom from the simple point Coulomb hydrogenic case. This project involves cooperative research of two groups of investigators who have complementary skills and facilities. The key collaborators are highly respected scientists who, for a number of years, have cooperated in the field of the research. Their cooperation has been highly successful and has resulted in several joint publications in refereed journals. The proposed study of multipole matrix element zeroes and resonances will shed light on the deviations from simple point Coulomb behavior in the case of electronic screening. This project is relevant to the objectives of the U.S.-Korea Cooperative Science Program which seeks to increase the level of cooperation between U.S. and Korean scientists and engineers through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit.
