Calculations of the energy levels and oscillator strengths of the Ne-like Fe Ion (Fe XVII)

Energy levels and oscillator strengths among the 27 fine-structure levels belonging to the (ls22s2)2p6, 2p53s, 2p53p and 2p53d configurations of the neon-like iron ion have been calculated using three atomic structure codes RCN/RCG, AUTOSTRUCTURE (AS) and GRASP. Relativistic corrections of the wave functions are taken into account in the RCN/RCG calculation. The results agree well with the available experimental and theoretical data. The accuracy of the three codes is analysed.
