Weighted oscillator strengths and lifetimes for the Si VIII spectrum

The weighted oscillator strengths ( g f ) and the lifetimes for Si VIII presented in this work were carried out in a multiconfiguration Hartree–Fock relativistic (HFR) approach. In this calculation, the electrostatic parameters were optimized by a least-squares procedure, in order to improve the adjustment to experimental energy levels. This method produces g f -values that are in good 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 Si VIII spectral lines.
