Abstract: The weighted oscillator strengths (gf) and the lifetimes for Ar III 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 gf-values that are in better agreement with intensity observations and lifetimes values that are closer to the experimental ones. In this work we presented all the experimentally known electric dipole Ar III spectral lines. (C) 2001 Published by Elsevier Science Ltd.
