Herein the energies of low-lying levels, wavelengths, transition rates, and line strengths for electric dipole allowed (E1) and forbidden (M1) lines in Ne- to Al-like ions of tantalum have been calculated using the GRASP2K package, which is based on the multiconfi guration Dirac–Hartree–Fock (MCDHF) method. From our radiative decay rates, we also calculated the radiative lifetimes of some levels. The present results are in good agreement with other available theoretical and experimental values. We predict new data for several levels where no other theoretical and/or experimental results are available, stipulating the necessity of precise measurements.

在此，使用 GRASP2K 包计算了钽的 Ne-to Al 类离子中电偶极子允许 (E1) 和禁止 (M1) 线的低能级能量、波长、跃迁率和线强度，这是基于多配置 Dirac-Hartree-Fock (MCDHF) 方法。根据我们的辐射衰减率，我们还计算了某些级别的辐射寿命。目前的结果与其他可用的理论和实验值非常吻合。我们预测没有其他理论和/或实验结果可用的几个级别的新数据，规定了精确测量的必要性。
