Abstract: Variational calculations are carried out with a multiconfiguration-interaction wave function to obtain the relativistic energies of the1s22 ln l1S(m)(n =2–6, m1–5)states for the beryllium isoelectronic sequence(Z =4–10). Relativistic corrections and the mass polarization effects are evaluated with the first-order perturbation theory. The identifications of the energy levels for1s22 ln l1S(m)(n =2–6, m1–5)states in the Be-like ions are reported. The oscillator strengths, transition rates and wavelengths are also calculated. The calculated results are compared with other theoretical and experimental data in the literature.
