| Abstract: | Variational calculations are carried out with a multiconfiguration-interaction wavefunction on the 1s22p2p 1De and 1s22p3p 3Pe states to obtain the energies including the mass polarization and relativistic corrections for the beryllium isoelectronic sequence (Z=4--10). The oscillator strengths,transition rates and wavelengths are also calculated. Our results are compared with other theoretical and experimental data in the literatures. The fine structure and hyperfine structure of 1s22p3p3Pe state are also explored. |
| Keywords: | Beryllium-like ion variational calculation fine structure hyperfine structure |
