This project is a continuation of work in progress to measure, using laser spectroscopy, magnetic dipole transition wavelengths within the ground terms of selected multiply-charged ions. The basic goals of the research are determination of the g-factor of an electron in a bound state of a highly charged ion, and precision laser measurement of the hyperfine structure of a high-Z one-electron ion. Immediate goals are fine-structure measurements on intermediate-Z ions, using a laser beam to induce the transitions in ions condensed to an ordered state at low temperature in a Penning ion trap. The research is done in collaboration with scientists from the Lawrence Berkeley National Laboratory and the Lawrence Livermore National Laboratory. Theoretical support is provided through a collaboration with an atomic structure theorist at the University of Texas, Pan American, an undergraduate institution.

该项目是正在进行的工作的继续，使用激光光谱学测量选定的多电荷离子的基态内的磁偶极跃迁波长。研究的基本目标是确定高电荷离子束缚态电子的g因子，以及高Z单电子离子超精细结构的精密激光测量。近期目标是对中间态Z离子进行精细结构测量，使用激光束在Penning离子阱中诱导低温下凝聚到有序态的离子的跃迁。 这项研究是与劳伦斯伯克利国家实验室和劳伦斯利弗莫尔国家实验室的科学家合作完成的。 理论支持是通过与得克萨斯大学泛美分校的原子结构理论家合作提供的。
