Transition energies from the /sup 1/S/sub 0/ ground state to the /sup 1/P/sub 1/ and /sup 3/P/sub 1/ excited states in the beryllium isoelectronic sequence are calculated using standard multiconfiguration Dirac-Fock (MCDF) theory. These predictions are then compared to those of the multiconfiguration relativistic random-phase-approximation (MCRRPA) theory and with experiment.
