| 摘 要： | 用HFR波函数对低密度类氢Ni27+等离子体与电子相互作用的KLn和KMn共振激发的双电子复合过程进行了细致的理论计算研究.根据可能的重要辐射衰变通道，分析了Ni27+等离子体Kα 型和Kβ 型辐射衰变的双电子复合速率系数随旁观电子主量子数n和轨道角动量量子数l与电子温度的变化行为，计算了Ni27+等离子体双电子复合过程的总速率系数.研究结果表明，在低密度条件下，Kα 型和Kβ型辐射衰变的分支双电子复合速率系数与旁观电子主量子数n和轨道角动量量子数l有重要关系，前者的分支速率系数远大于后者.

| Abstract: | The dielectronic recombination(DR) rate coefficients are investigated for low-density hydrogen-like Ni27+ at plasma temperatures 0.1—10 keV by the wavefunction from Hartree-Fock with relativistic Corrections(HFR) method. Based on the KLn and KMn resonance excitation, the partial DR rate coefficients of the DR processes are calculated by taking into account the important radiative decay tunnel including the Kα- and Kβ-type decays. It was found that the Kα- and Kβ-type radiative decays are important in the DR processes of hydrogen-like Ni27+. The partial DR rate coefficient of Kα processes is much larger than that of Kβ. |
