Abstract 2 The relativistic nuclear recoil, higher-order interelectronic-interaction, and screened QED cor- rections to the transition energies in Li-like ions are evaluated. The calculation of the relativistic recoil effect is performed to all orders in 1 /Z . The interelectronic-interaction correction to the transition energies beyond the two-photon exchange level is evaluated to all orders in 1 /Z within the Breit approximation. The evaluation is carried out employing the large-scale configuration- interaction Dirac-Fock-Sturm method. The rigorous calculation of the complete gauge invariant sets of the screened self-energy and vacuum-polarization diagrams is performed utilizing a local screening potential as the zeroth-order approximation. The theoretical predictions for the 2 p$_{j}$ − 2 s transition energies are compiled and compared with available experimental data in the range of the nuclear charge number Z = 10 − 60.
