基于准相对论Hatree Fock理论,采用Cowan程序详细计算了Co likeAu52+离子的双电子复合速率系数、自电离几率以及自电离能级。计算结果表明:由于径向波函数的穿透效应使得该离子自电离能级3d84l5s(l=s、p、d、f)升高,造成能级间隔不随外层激发电子轨道角动量的增加单调减小的异常现象,即Δ(E3d84l5d-E3d84l5p)>Δ(E3d84l5p-E3d84l5s)>Δ(E3d84l5f-E3d84l5d);双激发自电离态平均自电离几率具有特定的变化关系;双电子复合速率系数随着电子温度逐渐增加具有共振、高温收敛等特点,且双激发态轨道角动量大且宇称为奇的通道复合速率系数较大,其中辐射衰变通道为3d84fnd 3d9nd的复合过程占优势,在Te=0.49KeV时共振峰αDR=1.01×10-11(cm3sec-1)。
Based on the theory of quasi-relativistic Hatree Fock, the double electron recombination rate coefficient, the self-ionization probability and the self-ionization energy level of Co like Au52 + ions were calculated in detail using the Cowan program. The calculated results show that the ionosphere 3d84l5s (l = s, p, d, f) increases due to the penetrating effect of the radial wave function, resulting in the energy gap being not monotonic with the increase of the angular momentum of the outer excited electron orbit (E3d84l5p-E3d84l5s)> Δ (E3d84l5f-E3d84l5d). The average self-ionization probability of double-excitation self-ionization has a certain variation relationship. The rate of double-electron recombination rate increases with the increase of Electron temperature increases with resonance, high temperature convergence and other characteristics, and the double excited state orbital momentum and parochial channel complex rate coefficient larger, of which the radiation decay channel 3d84fnd 3d9nd composite process dominated Te = 0.49 The resonance peak αDR at KeV was 1.01 × 10-11 (cm3sec-1).
