Abstract Term energies, oscillator strengths, transition probabilities, and transition wavelengths among the low-lying states of (1s2)2s22p2, 2s22p3p, 2s2p3, 2s22p3s, and 2s22p3d 1,3,5 L L = S, P, D, F in N+, F3+, and Ne4+ ions were calculated by using the multiconfiguration Rayleigh-Ritz variation method and restricted variation method. The transition oscillator strengths and transition probabilities for the electric dipole transitions are both given in length and velocity gauges. Deviations between these two gauge values are discussed. The calculated atomic parameters are in good agreement with the observed experimental results and other theoretical data. Furthermore, the uncertainty of each electric dipole transition is estimated. Several uncertainties of transition parameters are improved when comparing with values from national institute of standards and technology NIST database. Atomic parameters presented in this paper should be useful for identifying the levels as well as for precise spectral modeling in astrophysical and laboratory plasmas in the future work.

N+、F3+ 和 Ne4+ 离子的能级和跃迁概率

摘要 (1s2)2s22p2, 2s22p3p, 2s2p3, 2s22p3s, and 2s22p3d 1,3,5 LL = S, P, D, F in N+, F3+ 和 Ne4+ 离子使用多重配置 Rayleigh-Ritz 变异法和受限变异法计算。电偶极跃迁的跃迁振荡器强度和跃迁概率均在长度计和速度计中给出。讨论了这两个规格值之间的偏差。计算的原子参数与观察到的实验结果和其他理论数据非常吻合。此外,估计每个电偶极子跃迁的不确定性。与国家标准技术研究院 NIST 数据库中的值相比,转变参数的几个不确定性得到了改善。本文中提出的原子参数应该有助于在未来的工作中确定水平以及在天体物理和实验室等离子体中进行精确的光谱建模。
