The first critical tests of many-body and correlated Quantum Electro-Dynamics (QED) in medium-Z atomic systems

中- z原子体系中多体和相关量子电动力学（QED）的首次关键测试。原子中量子电动力学效应的高阶项和相关项的计算遇到了主要困难。我们将首次对双电子QED临界敏感的中- z原子进行测量，并且在该区域的QED首次测试精度达到1%。这种准确性将允许对双电子系统，理论方法和最近观察到的QED理论与实验之间的差异有新的见解。这项提议是在最近利用电子束离子阱（EBITs）新功能的成功实验工作之后提出的。我们最近的出版物已经证明，这种新颖的方法可以对光与物质的相互作用产生新的见解。

The first critical tests of many-body and correlated Quantum Electro-Dynamics (QED) in medium-Z atomic systems. Major difficulties are being encountered in the computation of high-order and correlated terms of Quantum Electro-Dynamical effects in atoms. We will make the first measurements for medium-Z atoms critically sensitive to two-electron QED, and the first tests of QED in this region accurate to 1%. This accuracy will allow new insight into two-electron systems, theoretical approaches, and recent observed discrepancies between QED theory and experiment. This proposal follows recent successful experimental work using new capabilities of Electron-Beam Ion Traps (EBITs). Our recent publications have proven that this novel approach can yield new insight into the interaction of light with matter.
