Abstract
We have calculated energy levels of the ground state and the 2s2p excited states of berylliumlike ions with Z=10–92 using the relativistic configuration-interaction method. These calculations are based on the relativistic no-pair Hamiltonian which includes Coulomb and retarded Breit interactions and employ finite B-spline basis functions. Quantum electrodynamic and mass polarization corrections are also calculated. Good agreement between theory and experiment for the -2s2p transition energies is found throughout the isoelectronic sequence.
