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.

中 Z 原子系统中多体和相关量子电动力学 (QED) 的首次关键测试。在计算原子中量子电动力学效应的高阶和相关项时遇到了主要困难。我们将对双电子 QED 极其敏感的中 Z 原子进行首次测量，并且该区域的 QED 首次测试精度达到 1%。这种准确性将使人们对双电子系统、理论方法以及最近观察到的 QED 理论与实验之间的差异产生新的见解。该提案是继最近使用电子束离子阱（EBIT）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。
