Abstract: Abstract:Transition amplitudes for allowed transitions in Be-like ions are determined to second order within the framework of relativistic many-body perturbation theory. The calculations start with a V(N22) Dirac-Fock potential and include correlation corrections systematically. Multiconfiguration reference states are employed to account for the valence-valence correlations within the valence shell and perturbation theory is applied to systematically improve upon the wave functions. The transition amplitudes obtained in different gauges are in close agreement. The theoretical transition amplitudes agree well with experiment for all ions except for the neutral Be atom.
