Energy levels and radiative transitions of the K-shell excited sextet states in boron-like sulfur ion

Theoretical calculations are reported for energy levels and transition probabilities of the K-shell excited sextet series 6Se,o(m) and 6P,o,e(m)(m=1-7) for the astrophysically important element sulfur. Energy levels, fine structure splittings, and transition parameters of the high-lying sextet series 6Se,o(m) and 6P,o,e(m)(m=1-7) in boron-like sulfur ion are calculated with the multi-configuration Rayleigh-Ritz variation method. To obtain the accurate energy level, the relativistic corrections and mass polarization effect are included by using the first-order perturbation theory. Configuration structures of these sextet series are assigned according to the energies, percentage contributions of basis states to the eigenvector, relativistic effect corrections, and verification of fine structure splittings. The oscillator strengths, transition probabilities and wavelengths of electric-dipole transitions between 6So,e(m) and 6Pe,o(m) (m=1-7) states are also systematically calculated and discussed.The accepted manuscript in pdf format is listed with the files at the bottom of this page.
