摘要:

基于严格的QED方法,对类氦重离子的双光子跃迁进行了理论分析。特别注意的是考虑到在两次格林函数方法的衰变率的电子间相互作用校正。本文对类氦离子2^1S_0 -> 1^1S_0和2^3S_1 -> 1^1S_0的双光子跃迁进行了详细的计算。给出了总衰变率和谱分布。所得结果与实验值和以前的计算进行了比较。

英文摘要:

Based on a rigorous QED approach a theoretical analysis is performed for the two-photon transitions in heavy He-like ions. Special attention is paid to the interelectronic-interaction corrections to the decay rates that are taken into account within the two-time Green-function method. Detailed calculations are carried out for the two-photon transitions 2^1S_0 -> 1^1S_0 and 2^3S_1 -> 1^1S_0 in He-like ions within the range of nuclear numbers Z=28-92. The total decay rates together with the spectral distributions are given. The obtained results are compared with experimental values and previous calculations.
