A rigorous QED calculation of the two-photon exchange corrections to the 2p(1/2)- 2s transition energy in Li-like high- Z ions is presented. The contribution due to an exchange by more than two photons is evaluated within the Breit approximation. The resulting theoretical value of the 2p(1/2)- 2s transition energy in Li-like uranium is found to be 280.44(20) eV.
本文给出了对类锂高Z离子中2p(1/2)-2s跃迁能量的双光子交换修正的严格量子电动力学计算。在Breit近似下评估了由两个以上光子交换引起的贡献。发现类锂铀中2p(1/2)-2s跃迁能量的理论值为280.44(20)电子伏特。
