本研究的重点是新的和持续的实验测试的量子电动力学和正电子的相对论束缚态形式。将在200 ppm水平上进行两次系统测试,以解决该组获得的当前值与理论值之间的差异。对激发态正电子的高精度光谱分析将在n=2精细结构区间的测量中继续进行。
英文摘要
This research focuses on new and continuing experimental tests of quantum electrodynamics and relativistic bound-state formalism in positronium. Two systematic tests at the 200 ppm level will be made to address differences between the current value obtained by this group and the theoretical value. High precision spectroscopy of positronium in excited states will be continued with measurement of the n=2 fine structure intervals.
