We consider theoretically the process of two-electron one-photon (TEOP) transitions to the ground state with the emission of a single $K_{\alpha \alpha }$ photon in a He-like sequence of atomic ions: from boron to uranium. The corresponding transition probabilities and transition energies are calculated within the QED theory. The calculations of the transition probabilities are performed in various gauges. The intensity ratios between the TEOP transitions and the other major transitions are presented.

类氦离子中两电子单光子跃迁概率的 QED 计算

我们在理论上考虑了双电子单光子 (TEOP) 跃迁到基态的过程，同时发射单个 ${钾}_{\alpha \alpha }$类似 He 的原子离子序列中的光子：从硼到铀。相应的跃迁概率和跃迁能量在 QED 理论中计算。转移概率的计算在各种规格中进行。显示了 TEOP 过渡和其他主要过渡之间的强度比。
