Relativistic andmass-polarization effects on the energy are evaluated as the first-order perturbation theory. Ourpredicted excitation energies are compared with previous experimental results in the literature.展开更多

In most cases, the agreementbetween the oscillator strengths values from the length and velocity formula is up to four or fivedigit. Our results are aiso in good agreement with previous theoretical data available in theliterature.展开更多
