We have calculated energy levels of the 2s{sup 2}{sup 1}S{sub 0} ground state and the 2s2p{sup 1,3}P{sub 1} excited states of berylliumlike ions with Z=10{endash}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 2s{sup 2}{sup 1}S{sub 0}{minus}2s2p{sup 1,3}P{sub 1} transition energies is found throughout the isoelectronic sequence. {copyright} {ital 1997} {ital The American Physical Society}
