【 摘 要 】

A new set of oscillator strengths and transition probabilities for EUV spectral lines of seven times ionized tungsten (W VIII) is reported in the present paper. These results have been obtained using the pseudo-relativistic Hartree-Fock (HFR) method combined with a semi-empirical optimization of the radial parameters minimizing the discrepancies between computed energy levels and available experimental data. The final physical model considered in the calculations has been chosen further to a detailed investigation of the configuration interaction in this atomic system characterized by complex configurations of the type 4f¹⁴5s²5p⁵, 4f¹⁴5s²5p⁴nl, 4f¹⁴5s5p⁶, 4f¹³5s²5p⁶, 4f¹³5s²5p⁵nl and 4f¹²5s²5p⁶nl (nl = 5d, 6s).
