摘要：

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 2P1/2-2S transition energy in Li-like uranium is found to be 280.44(20) eV.
