摘要: 在自旋轨道劈裂阵模型下，通过类铜组态理论计算出类镍Gd36+的双电子复合速率系数，得出其在电子温度 0.02~5keV 范围内的变化规律，并分析了影响双电子复合速率系数的主要因素是相应的自电离系数和离化势，这为等离子体的诊断提供了一种新的方法。Abstract: The calculations of the rate coefficients for dielectronic recombination (DR) along the NiI isoelectronic sequence in the ground state Gd36+ through Cu-like inner-shell excited configurations were performed using the model of SOSA. Collisional transitions following electron capture are neglected. The trend of the DR rate coefficients was founded with the change of the electronic temperature in the range of (0.02~5)keV .The main factor which effected the DR coefficients was analyzed. This is the relative auto-ionization coefficients and auto-ionized energy. These will provide a new method for diagnose the parameters.
