Spectra of highly-charged Mo ions excited in the 6.7–14.3 nm wavelength region by focusing Nd:YAG laser light pulses (λ=1064 nm, 10 ns) have been recorded and investigated. A spatio-temporally resolved laser-produced plasma spectroscopy technique was used. The observed spectra are composed of many lines that correspond to Mo⁷⁺-Mo¹²⁺ ions belonging to the 4s-np, 4p-nd (n = 5–8), and 4p-ms (m = 6–8) transition arrays. Only 4p-(5,6)s and 4p-(5,6)d resonance transition of Mo⁷⁺ and Mo⁸⁺ were analyzed before. The spectrum investigations were based on the Hartree-Fock (HF) method within the framework of the pseudo-relativistic corrections (HFR) using Cowan's codes. Double excitation in Mo¹²⁺, Mo¹³⁺, and Mo¹⁴⁺ were also worthy of inclusion because of their important contributions. To obtain the best fitting with the spectral features, the possible contributions from the 4s4p^k4d metastable state ions within the plasma were included. Comprehensive calculations were performed and several previously unclassified lines have been identified for the first time. A steady-state collisional-radiative (CR) model was devoted to obtaining the plasma parameters and interpreting the emitted spectrum. The theoretical simulated spectrum agrees reasonably well with the experimental profile, which can indicate the possibility of use for plasma diagnostics. The results should be beneficial for future assessment and comparisons as well as spectroscopic diagnostics of hot plasmas in tokamak plasmas and fusion research.

通过聚焦 Nd:YAG 激光脉冲 ( λ =1064 nm, 10 ns)在 6.7-14.3 nm 波长区域激发的高电荷 Mo 离子的光谱已被记录和研究。使用了时空分辨激光产生等离子体光谱技术。观察到的光谱由许多谱线组成，这些谱线对应于属于 4s- n p、4p- n d ( n  = 5–8) 和 4p- m s ( m  = 6–8 ) 的Mo ⁷⁺ -Mo ¹²⁺离子) 过渡数组。Mo ⁷⁺和Mo ⁸⁺只有4p-(5,6)s和4p-(5,6)d共振跃迁之前分析过。频谱调查基于使用 Cowan 代码的伪相对论校正 (HFR) 框架内的 Hartree-Fock (HF) 方法。Mo ¹²⁺、Mo ¹³⁺和Mo ¹⁴⁺中的双激发也值得包括在内，因为它们的重要贡献。为了获得与光谱特征的最佳拟合，来自 4s4p ^k的可能贡献包括等离子体内的 4d 亚稳态离子。进行了综合计算，并首次确定了几条以前未分类的线路。稳态碰撞辐射 (CR) 模型致力于获得等离子体参数和解释发射光谱。理论模拟光谱与实验曲线相当吻合，这可以表明用于等离子体诊断的可能性。这些结果应该有利于未来的评估和比较以及托卡马克等离子体和聚变研究中热等离子体的光谱诊断。
