Description
We have improved our previous mixed configuration-interaction and perturbation-theory (CI+MBPT) methods by including all second-order Coulomb and lowest-order Breit terms. The method is applied in calculations of E1 matrix elements for the two 2s2→2s2p transitions of light Be-like ions. The results are in good agreement with experiments and other precise calculations. The length and velocity transition amplitudes are also more consistent
