Abstract

Large-scale relativistic configuration-interaction method combined with many-body perturbation theory is
consistently applied to calculations of the energy levels of the ground and inner-L-shell excited states of
berylliumlike ions in the range 10 Z 92. The quantum electrodynamics, nuclear recoil, and frequency-
dependent Breit corrections are taken into account. The obtained results are supplemented with the systematical
estimation of the uncertainties.
