Atomic structures and radiative properties of He like Ar XVII in the presence of dense plasma environments and external magnetic field have been presented within the framework of the relativistic theory. For this purpose, the relativistic configuration interaction method by incorporating the generalized b-potential and external magnetic field has been implemented. Plasma screening effect on 1sS → 1s2p P transitions of Ar XVII ion in the presence of an external magnetic field has been investigated. We also studied the Zeeman splitted energies and predicted the excitation energies of Ar XVII ion for the magnetic sublevels 1s2p P (M = 0), P (M = 0, ±1), P (M = 0, ±1, ±2), P (M =0, ±1). Our calculated results are in excellent agreement with National Institute of Science and Technology (NIST) database and other theoretical available data.

稠密等离子体环境和外磁场对Ar XVII原子结构和辐射性能的影响

在相对论框架内，提出了在稠密等离子体环境和外部磁场存在下，Ar XVII 等 He 的原子结构和辐射特性。为此，采用了结合广义b势和外部磁场的相对论构型相互作用方法。研究了在外部磁场存在下，Ar XVII 离子的 1sS → 1s2p P 跃迁的等离子体屏蔽效应。我们还研究了塞曼分裂能量并预测了 Ar XVII 离子在磁性子能级 1s2p P (M = 0), P (M = 0, ±1), P (M = 0, ±1, ±2) 的激发能，P（M=0，±1）。我们的计算结果与美国国家科学技术研究院 (NIST) 数据库和其他理论可用数据非常一致。
