US-France Cooperative Research: Photoionization Studies of Excited Atoms and Ions Using Synchrotron Radiation

该奖项将支持卫斯理大学Thomas Morgan博士和法国奥赛原子与离子光谱实验室Francois Wuilleumier博士在原子物理学方面的合作研究。研究人员提出了一系列的实验来研究激光激发原子的光电离以及单电荷和双电荷原子的光电离。关于离子的性质、结构以及与原子、其他离子和辐射的相互作用的信息对等离子体和天体物理科学非常重要。在这个项目中，同步辐射与激光激发离子将被用来探测原子系统的结构和光子与激发原子和带电粒子相互作用的动力学。摩根博士可以使用超级加速器，世界上第一个第三代同步辐射设备，刚刚在法国投入使用。法国研究人员维卢米耶博士是在原子物理学中使用同步辐射的先驱；他的奥赛实验室是国际公认的。这一研究结果将对理解受激原子和离子在自由状态下的结构和动力学有价值。

This award will support collaborative research in atomic physics between Dr. Thomas Morgan, Wesleyan University and Dr. Francois Wuilleumier, Laboratoire de Spectroscopie Atomique et Ionique, Orsay, France. The investigators propose a series of experiments for the study of the photoionization of laser-excited atoms and the photoionization of singly and doubly-charged atoms. Information on the properties of ions, their structure and interactions with atoms, other ions and radiation, is important for the plasma and astrophysical sciences. In this project, synchrotron radiation in conjunction with laser excited ions will be used to probe the structure of atomic systems and the dynamics of the interactions of photons with excited atoms and charged particles. Dr. Morgan will have access to the SUPER-ACO, the world's first third generation synchrotron radiation facility, which is just being commissioned in France. Dr. Wuilleumier, the French investigator, is a pioneer in the use of synchrotron radiation in atomic physics; his Orsay lab is internationally recognized. Results of this research will be of value for the understanding of the structure and dynamics of excited atoms and ions in the free state.
