“…important low-lying excited configurations. Accurate evaluation of theoretical transition rates belonging to such core-excited configuration is quite challenging and very few attempts have been made in the past [81,82] and we can even see that in table 2 the 4 P 5/2 term belonging to 1s( 2 S)2s2p( 3 P) is missing for all the ions in the NIST column there. Thus, in this work special focus is given in the evaluation of all the terms of 1s2s2p configuration.…”

We have carried out atomic structure calculations using systematically enlarged multiconfiguration Dirac- Fock wavefunctions of Li-like ions of the most prominent plasma impurities (Ar, Ti, Fe, Ni, Kr and W) found in presently working tokamaks. Relativistic Breit interaction and quantum electrodynamic (QED) corrections such as vacuum polarization and self-energy corrections are also included in the calculations prior to the evaluation of low lying energy levels, transition probabilities, oscillator strengths and line strengths. Selective radiative data for electric dipole and magnetic quadrupole transitions are also reported. Special emphasis is given in the computations of fundamental quantities such as oscillator strengths as they are widely used in atomic data and analysis structure (ADAS) databases to evaluate quantities such as effective collision strengths. Present com- puted values are compared with existing available results on NIST database and few similar earlier computations and a good agreement has been found. We believe that the detailed atomic data with the relativistic and QED corrections will assist in spectroscopic studies such as accurate line identification and plasma modelling work in tokamak plasma, laser induced breakdown spectroscopy (LIBS), highly charged ions clocks and astrophysical observations.
