Energies, fine structures, and transitions of the core-excited sextet states 6Se,o(n) and 6Pe,o(n) (n=1-5) of B-like ions

- Energy and transition data of core-excited sextet states of B-like ions are studied.
- Relativistic corrections, mass polarization effects are included in the calculation.
- Radiative rates and transition wavelengths are discussed with the increase of Z.
- Variation trend of transition rates and wavelengths are present with the n increase.
- Some energy levels and transition data are reported for the first time.

A comprehensive theoretical study of atomic characteristics of energy levels and transitions for the core-excited 6Se,o(n) and 6Pe,o(n) (n=1-5) states of the boron isoelectronic sequence (Z=6-14) are investigated by the Rayleigh-Ritz variation method and multi-configuration interaction wavefunctions. The relativistic corrections and mass polarization effects are included by first-order perturbation theory. The configuration structures of the high-lying sextet series 6Se,o(n) and 6Pe,o(n) (n=1-5) of the B-like ions are assigned. The transition rates and wavelengths for the electric dipole transitions 6Se,o(n)-6Po,e(n) (n=1-5) of the B-like ions are calculated and compared with currently available theoretical and experimental data. Furthermore, the radiative transition rates and wavelengths for the important dipole transitions are discussed with the increase of nuclear charge number Z. The calculations will provide useful data for identification of spectral lines arising from the solar atmosphere and the experimental study in future work.
