Atomic spectral data of six argon ions from Ar⁹⁺ to Ar¹⁴⁺ are calculated by combining the relativistic multi-configuration interaction method and the many-body perturbation theory (FAC-MBPT) method. Transitions from shell number n=2 to shell numbers n=3, 4, 5, and 6 are investigated where relativistic effects, correlation effects, and QED effects are applied. Experimental transition lines often demonstrate blending and overlapping that confuse the identification of spectral lines in absence of accurate theoretical data. This elucidates the importance of having accurate atomic calculations in order to carry out reliable modelling for laboratory and astrophysical spectra of Ar ions. When compared with published data, our findings offer the best agreement with experimental observations; thereby recommend the use of FAC-MBPT calculation method to produce accurate theoretical data for the six investigated Ar ions.

结合相对论多构相互作用法和多体扰动理论（FAC-MBPT），计算了从Ar ⁹⁺到Ar ¹⁴⁺的6个氩离子的原子光谱数据。从外壳编号n = 2到外壳编号n的转换研究了应用相对论效应，相关效应和QED效应的= 3、4、5和6。实验过渡线经常表现出混合和重叠，这在缺乏准确理论数据的情况下混淆了光谱线的识别。这阐明了进行精确的原子计算以对Ar离子的实验室和天体光谱进行可靠建模的重要性。与已发表的数据进行比较时，我们的发现与实验观察结果最为吻合。因此建议使用FAC-MBPT计算方法为所研究的六个Ar离子产生准确的理论数据。
