Abstract Radiative transition wavelengths and rates as well as Auger transition probabilities for the deexcitation of the 1 s2 s 22 p, 1 s2 s2 p 2, and 1 s2 p 3 configurations of Be-like ions have been calculated relativistically by the multiconfiguration Dirac-Fock method. Eight ions with atomic numbers in the range 6 ⩽ Z ⩽ 26 are considered. The transverve Breit interaction and quantum electrodynamic corrections are taken into account in the energy calculations. The transition rates are computed in intermediate coupling with configuration interaction within the same complex. Both Coulomb and generalized Breit interactions are included in the evaluation of relativistic Auger matrix elements. The dielectronic satellite intensity factors and line fluorescence yields are also calculated.
