High-lying core-excited quartet states in li-like N~(4+) and F ~(6+) ions

摘要

The variational method with mutilconfiguration interaction wave function is used to obtain the energies, fine structures, and hyperfine structures of highlying core-excited quartet states 1s2|n|' 4P~o(m) (m = 1-5) and 1s2pnp ~4P(m) (m = 1-5) in Li-like N~(4+) and F~(6+) ions, including the mass polarization and relativistic corrections. Restricted variational method is carried out to extrapolate a better energy. The oscillator strengths, lifetime, wavelengths, fine structure, and hyperfine structure for this system are also investigated to compare with other theoretical and experimental data in the literature.
