COSTA, I. V. L.; CAVALCANTI, G. H.  and  TRIGUEIROS, A. G.. Weighted oscillator strengths and lifetimes for the neutral oxygen spectrum, O I. Braz. J. Phys. [online]. 2001, vol.31, n.1, pp.48-50. ISSN 0103-9733.

The weighted oscillator strengths (gf) and the lifetimes for O I presented in this work were obtained in a multiconfiguration Hartree-Fock relativistic (HFR) approach. In this calculation, the electro-static parameters were optimized by a least-squares procedure, in order to improve the adjustment to experimental energy levels. This method produces gf-values that are in better agreement with intensity observations and lifetime values that are closer to the experimental ones. In this work we present all the experimentally known electric dipole atomic transitions and energy levels for the O I spectrum.
