U.S.-Korea Cooperative Research: Precision Spectroscopy of Atomic Cesium in High-Gradient and High-Intensity Electromagnetic Fields

该奖项将资助科罗拉多大学物理系和天体物理实验室联合研究所的Carl E. Wieman博士与高丽大学物理系的Donghyun Cho博士进行为期24个月的合作研究项目，该项目涉及对受各种电磁场影响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540纳米的非常强的、可调谐的窄带激光照射时产生的现象。除了产生关于铯原子本身的高精度数据外，拟议的研究将使用在测量科学领域具有普遍应用的新思想和新技术。合作者对原子系统的高精度光谱学有共同的兴趣。赵博士参与了将在科罗拉多大学使用的设备的建设，并将在韩国开发其他设备，以提高拟议实验的灵敏度。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。韩国参与该项目得到了韩国科学工程财团（KOSEF）的支持。＊＊＊

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). ***
