Collaborative Research: Laser Spectroscopy of Hydrogenic and Heliumlike Ions

这个合作项目的科学目标是精确测量中间Z类氢离子和类氦离子n=2能级之间的某些跃迁能量。这些测量将测试单电子和双电子系统中的量子电动力学计算，特别是高阶束缚修正。这项工作对于解释氢和氦的精密光谱，从而获得里德堡常数和精细结构常数的值具有重要意义。将使用的方法包括对佛罗里达州立大学范德格拉夫加速器的快速剥箔离子束进行激光光谱分析。这项工作将涉及来自佛罗里达州立大学和佛罗里达农工大学的研究生和本科生。

The scientific aim of this collaborative project is to carry out precise measurements of certain transition energies between the n=2 levels on intermediate Z hydrogen-like and helium-like ions. The measurements will test quantum electrodynamic calculations, particularly of higher-order binding corrections, in one- and two-electron systems. The work has relevance to the interpretation of precision spectroscopy of hydrogen and helium and hence to obtaining values for the Rydberg constant and the fine structure constant. The method to be used involves laser spectroscopy of fast, foil-stripped ion beams from the Florida State Van de Graaff accelerator. The work will involve graduate and undergraduate students from Florida State and Florida A&M Universities.
