9421662 Wieman This award provides funds to permit Dr. Carl E. Wieman, Department of Physics and Joint Institute for Laboratory Astrophysics, University of Colorado, to pursue with Dr. Donghyun Cho, Department of Physics, Korea University, for 24 months, a program of cooperative research involving high-precision spectroscopic measurements on spin-polarized cesium atoms which are subjected to various electromagnetic fields. The collaborators will use apparatus which they developed to study phenomena produced when these cesium atoms are subjected to very intense, tunable, narrowband, laser light at 540 nm. In addition to producing high-precision data about the cesium atom itself, the proposed research will use new ideas and techniques that will have general application in the field of measurement science. The collaborators have a common interest in high precision spectroscopy of atomic systems. Dr. Cho has participated in construction of the apparatus to be used at the University of Colorado and will develop, in Korea, additional equipment which will lead to improved sensitivity in the proposed experiments. 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. Korean participation in the project is supported by the Korea Science and Engineering Foundation (KOSEF). ***

9421662维曼该奖项提供资金，以允许科罗拉多大学物理系和联合实验室天体物理研究所的卡尔·E·维曼博士与韩国大学物理系赵东贤博士进行为期24个月的合作研究计划，该计划涉及对处于各种电磁场中的自旋极化铯原子进行高精度光谱测量。合作者将使用他们开发的仪器来研究当这些铯原子受到非常强的、可调的、窄带的540 nm激光照射时产生的现象。除了产生有关铯原子本身的高精度数据外，拟议的研究还将使用新的想法和技术，这些新想法和技术将在测量科学领域得到普遍应用。合作者对原子系统的高精度光谱学有着共同的兴趣。赵博士参与了将在科罗拉多大学使用的仪器的建造，并将在韩国开发额外的设备，这些设备将在拟议的实验中提高灵敏度。该项目与美韩合作科学计划的目标相关，该计划旨在通过交流科学信息、想法、技能和技术以及通过在互利问题上的合作来提高美国和韩国科学家和工程师之间的合作水平。韩国参与该项目得到了韩国科学与工程基金会(KOSEF)的支持。***
