Transition spectral parameters of In-like Ba, La and Ce ions

The spectral parameters (energy levels, wavelengths, transition probabilities, line strengths and oscillator strengths) of resonance lines for Ba VIII, La IX Ce X have been performed using the multiconfiguration Dirac-Hartree-Fock method, contributions quantum electrodynamics Breit interactions correction are taken into considered. calculated results energy levels wavelengths in good agreement with experimental values other calculation. number considered is larger than that any experiment calculations. also where no theoretical available.
