高剥离态离子谱学研究

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． 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.
