U.S.-Japan Cooperative Research: Charge-Exchange Reactions and Giant Resonances

9315127 Janecke该奖项支持密歇根大学物理系Joachim Janecke教授与日本大阪大学核物理研究中心（RCNP） Mamoru Fujiwara教授为期两年的合作研究项目。除Janecke教授外，密歇根大学的一名博士后和一名研究生将访问日本参与联合研究项目。密歇根大学的研究人员将在新的环形回旋加速器设施和大阪大学的新磁谱仪Grand Raiden上进行与电荷交换反应和巨共振特性研究相关的实验。RCNP设施中可用的粒子能量有利于自旋翻转跃迁。该实验旨在研究Gamow-Teller共振的微观结构以及电荷-反应机制在等矢量非自旋翻转、自旋翻转和张量相互作用方面的特征，这是美国印第安纳大学回旋加速器设施首席研究员在过去几年中所做工作的延伸和延续。这些实验将产生新的数据，可能阐明等压模拟态的特征。＊＊＊

9315127 Janecke This award supports a two-year cooperative research project between Professor Joachim Janecke, Department of Physics, University of Michigan, and Professor Mamoru Fujiwara, Research Center for Nuclear Physics, (RCNP) Osaka University, Osaka, Japan. In addition to Professor Janecke, a postdoctoral fellow and a graduate student from the University of Michigan will visit Japan to participate in the joint research project. The Michigan researchers will perform experiments related to the study of charge-exchange reactions and the properties of giant resonances at the new Ring Cyclotron Facility and the new magnetic spectrometer Grand Raiden at Osaka University. The particle energy available at the RCNP facility favors spinflip transitions. The proposed experiments to investigate microscopic structures of Gamow-Teller resonances and characteristics of the charge-reaction mechanisms in terms of isovector non-spinflip, spinflip, and tensor interactions represent an extension and continuation of work performed by the U.S. principal investigator at the Indiana University Cyclotron Facility over the past several years. These experiments will yield new data that may shed light on the character of isobaric analog states. ***
