Weighted oscillator strengths and lifetimes for the Si X spectrum

The weighted oscillator strengths (gf) and the lifetimes for Si X presented in this work were carried out in a multiconfiguration Hartree-Fock relativ istic (IIFR) approach. In this calculation, the electrostatic parameters we re optimized by a least-squares procedure, in order to improve the adjustme nt to experimental energy levels. This method produces gf-values that are i n better agreement with intensity observations and lifetime values that are closer to the experimental ones. In this work we presented all the experim entally known electric dipole Si X spectral lines. (C) 1999 Elsevier Scienc e Ltd. All rights reserved.
