摘要: 镁铝类氢类氦类锂离子经中间双激发态进行的双电子复合过程在用双示踪元素谱线强度比研究ICF电子温度中占有很重要的地位。计算了双电子复合经不同Rydberg态跃迁通道的复合速率系数,并给出不同离化度的总的双电子复合速率系数的变化规律,比较了它们在不同电子温度和不同跃迁通道的异同,对研究X射线激光、等离子体温度诊断等诸多应用领域提供了有价值的原子数据。Abstract: The physical process of dielectronic recombination for Hlike, Helike and Lilike ions of Mg and Al in the medial double ionized states plays an important role in studying laser inertial confinement fusion (ICF) electronic temperature by the method of the double traced materials isoelectronic Xray spectrum. This paper presents the dielectronic recombination rate coefficients with different Rydberg configuration states channels. The rate coefficients of different ionized states are given and compared with variable temperature and transition channels.
