Abstract
Variational calculations using multiconfiguration interaction wave functions are carried out on the 1s2s2P) and the 1s2S) states for the Be i isoelectronic sequence from Z=3–10. For each species, the upper bound, the nonrelativistic energy, the transition wavelength, the oscillator strengths, the radiative lifetime, the fine structure, the hyperfine parameters, and coupling constants are reported. The relativistic corrections and the mass polarization are included. The upper bounds and the nonrelativistic energies obtained are much lower than the previously published values for each member of the Be i isoelectronic sequence. The calculated fine-structure results are compared with the existing theoretical and experimental data. The predicted results of the hyperfine structure in this investigation provide useful data in the experimental analysis of fine-structure transitions between the 1s2s2P) and the 1s2S) states for berylliumlike isoelectronic sequence spectra.
