Theoretical calculation of wavelengths and transition probabilities for magnesium-like Cu XVII

The energy levels of magnesium-like ion Cu X VIII in n = 3complex configurations are computed by multi-configuration Hartree-Fock with relativistic corrections (HFR) method. The Slater parameters are optimized with the least-square-fit(LSF) technique based on the available experimental data. With these new parameters, the wavelengths, oscillator strengths and transition probabilities for transitions 3s(2)-3s3p, 3s3p-3p(2), 3p(2)-3p3d, 3s3d-3p3d, 3p3d-3d(2) in n = 3complex configurations for magnesium-like Cu XVIII are predicted.
