“…Due to interaction of plasma with the ITER wall it is being predicted that W will be a dominant impurity ion in the plasma thus, huge efforts are underway to develop plasma diagnostics based on W ions [35,36]. Thus, Li-like impurity ions observed in the above mentioned tokamaks have remained a subject of many theoretical computations in the past [18,[37][38][39][40][41][42][43][44]. Apart from tokamak and astrophysical plasma there has been growing interest in plasma produced usinghigh power lasers called as laser induced plasmas (LIPs).…”

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.
