Spectroscopic data for atomic tungsten transitions of interest in fusion plasma research

Résumé

Transition probabilities for W I lines of potential interest for fusion plasma diagnostics are reported in the present paper. They have been obtained using the relativistic Hartree-Fock approach including core-polarization effects. The accuracy of the results has been assessed through comparison between two different physical models and through detailed comparison with available experimental lifetimes and transition probabilities. These results represent the first complete set of spectroscopic parameters computed for the very complex tungsten atomic system. The new data are expected to be useful for plasma modeling in fusion reactors such as ITER.
