Abstract
The fully relativistic multi-configuration Dirac–Fock (MCDF) method is employed to compute the excitation energies and radiative rates for Li-like ions (57 ≤ Z ≤ 92). Relativistic corrections quantum electrodynamics (QED) and Breit corrections have been included in the calculations. We have presented the lowest 24 fine structural level energies and radiative data for electric dipole (E1) transitions among these levels. We have compared our results with results compiled by NIST as well as with other results available in the literature. We have also performed analogous calculations for energy levels by using flexible atomic code (FAC), to assess the accuracy of our results. Further, we have identified soft x-ray (SXR) and extreme ultra-violet (EUV) spectral lines within listed E1 transitions. We strongly believe that our presented data will be helpful in future works related to high Z lithium ions.
