Our results of 1s22s and 1s22p states agree well with the high-precision results of Yan et al. Based on calculating the first-order corrections to the energy from relativistic and mass-polarization effects,we estimate the higher-order relativistic contribution and QED correc-tion to the energy under a hydrogenic approximation. The transition energies,wavelengths and oscil-lator strengths for the 1s22s-1s2np (n≤9) transitions of this ion are calculated. The results agree with the experimental data available in literature satisfactorily. By combining with quantum defect theory,our theoretical predictions on the energy and oscillator strength of this ion are extrapolated to the whole energy region including continuous states.展开更多
