摘要: 利用“星光”Ⅰ激光装置,聚焦激光束于真空室内平面箔靶,产生高离化态等离子体,分别用四个不同晶格间距的平晶摄谱仪和1m掠入射光栅谱仪测量了_(22)Ti、_(26)Fe、_(28)Ni、_(29)Cu、_(30)Zn、_(32)Ge等中Z元素及_(72)Hf、_(73)Ta、_(74)W、_(75)Re等高Z元素的高离化态离子发射谱,其波长为3.6~300A分别用组态相互作用的Hartree-Fock-Relativistic(HFR)方法和多组态的Dirac-Fock方法分析辨认发射谱中的线跃迁,用自旋轨道劈裂的未分辨跃迁组理论分析发射谱中的带结构,归类了六个中Z元素类钠直至类氦离子的数百条跃迁线,以及四个高Z元素的类钻、类镍、类铜直至类锗离子的线跃迁和跃迁带.

Thespectra in the range of 3. 6-300A were recorded by using four flat crystal spectrographyswith different 2d spacting...Abstract: The soft X-ray emission spectra from very highly stripped ions of the medium Z elements of_(22)T,_(26)Fe,_(28)Ni,_(29)Cu,_(30)Zn and_(32)Ge, and the high-Z elements of_(72)Hf,_(73)Ta,_(74)Wand_(75)Re have been observed in laser-produced plasmas generated by focusing a Nd-glasslaser beam onto the surface of the plane solid targets at the "Xing Guang" laser facility.
