Abstract Employing two state-of-the-art methods, multiconfiguration Dirac–Hartree–Fock and second-order many-body perturbation theory, highly accurate calculations are performed for the lowest 200 fine-structure levels arising from the 2 l 7 , 2 l 6 3 l ′ and 2 l 6 4 l ′ configurations of the fluorine-like isoelectronic sequence with Z = 31 − 35. Complete and consistent atomic data, including excitation energies, lifetimes, wavelengths, and E1, E2, M1, M2 line strengths, oscillator strengths, and transition rates among these 200 levels are provided. Comparisons are made between the present two data sets, as well as with other available experimental and theoretical values. The present data are accurate enough for identification and deblending of emission lines involving the n = 3 , 4 levels, and are also useful for modeling and diagnosing fusion plasmas.
