论文摘要
在这项研究中,已经对最低的71个类似Na的Ar $^{7+} $,KR $^{25+} $和XE $^$^{43+} $ imions的na样AR $^{7+} $,对最低的71个状态进行了全面计算,超细结构常数,LandéG$ _J $因子和同位素转移。辐射参数,即在这些水平中的电和磁偶极子和四极杆过渡的辐射参数,波长,波长,振荡器强度和寿命。所考虑的状态包括$ 1S^2s^22p^6nl $,其中n = 3至9和l = s至i以及完全相对论的多浓度dirac fock方法集成在最新版本的通用相对论原子结构软件包中。还包括相对论计算,即布里特相互作用和量子电动力学效应,并分析它们对能量的影响。为了检查MCDF结果的可靠性,我们使用集成在FlexI原子密码中的许多身体扰动理论方法进行了另一项计算。两种获得的计算与先前的理论和实验结果之间进行了详尽的比较,无论在任何地方都可以观察到良好的一致性。本计算将大大扩展这些类似NA的离子的现有结果,因为大多数结果首次报告了大多数结果,我们认为我们的结果很高准确性,对等离子体和天体物理学的光谱分析和诊断将是有益的。
In this study a comprehensive calculations of energies, hyperfine structure constants, Landé g$_J$ factors and isotope shifts have been performed for the lowest 71 states of Na-like Ar$^{7+}$, Kr$^{25+}$ and Xe$^{43+}$ ions. Radiative parameters viz., transition rates, wavelengths, oscillator strengths and lifetimes are also estimated for the electric and magnetic dipole and quadrupole transitions among these levels. The states under consideration includes $1s^2s^22p^6nl$ where n = 3 to 9 and l = s to i and fully relativistic multiconfiguration Dirac Fock method integrated in the latest version of general purpose relativistic atomic structure package is used. The relativistic calculation viz., Briet interactions and quantum electrodynamics effects are also included and their effects on energies are analysed. To inspect the reliability of MCDF results, we carried out another calculations using many body perturbation theory method integrated in Flexi Atomic code. A thorough comparison between the two obtained calculations and with the previous theoretical and experimental results, wherever available, is carried out and a good agreement is observed. The present calculations will considerably extend the already existing results for these Na-like ions as most of the results are reported for the first time Further, we believe that our results are of high accuracy and will be beneficial for spectral analysis and diagnosis in plasma and astrophysics.
