【摘要】 本文用全量子力学方法计算了Ti、Cr类He总双电子复合速率系数和态 态双电子复合速率系数,给出了Ti、Cr类He态 态双电子复合速率系数与旁观主量子数、与原子实耦合对称性,以及与谱项多重性、对称性和角动量之间的关系。计算结果显示1s2pnp→1s2np和1s2pnd→1s2nd两衰变通道的双电子复合速率系数占总双电子复合速率系数的75%,成为对总双电子复合速率系数贡献最大的两个复合通道。本文得到了能用于冕区等离子体诊断目的的Ti、Cr类He双电子复合数据。更多还原

【Abstract】 The full quantum mechanics method is used to calculate the state-to-state and the total dielectronic recombination rate coefficients for He-like Ti and Cr. The relations between the dielectronic recombination rate coefficients and the different coupling parameters of spectral terms are studied. It is shown that the two recombination channels 1s2pnp→1s~2np and 1s2pnd→1s~2nd provide 75% of the total dielectronic recombination rate coefficients. The state-to-state and the total dielectronic recombination rate coefficient, which can be used in the electronic temperature diagnostics of corona plasma, are also obtained.更多还原
