摘要: 研究了组态相互作用和相对论修正对低Z(原子序数)及中等Z类He离子双电子谱的影响,使用准相对论及非相对论的Hartree-Fock自洽场方法计算了描写双电子伴线的原子参数。计算结果表明,(1)组态相互作用对类He离子双电子诺有显著影响;(2)对中等Z的类He离子,仅以能量微扰的形式计入相对论修正是不足够的,为了获得更加精确的计算结果,不仅要考虑相对论修正对单、双激发态能量的影响,而且要考虑该效应对径向波函数的影响。

Abstract: Effects of condguration mixing and relativistic corrections on the dielectronic satellite spectra have been studied for the He-like ions with low-and medium-Z. The atomic Parameters characterizing the dielectronic satellite lines are evaluated by using the send-and non-relativistic Hartree-Fock models. The results calculated show that (1) configuration mixing has an important effect on the dielectronic satellite spectra for the He-like ions, and (2) for the medium-Z He like ions, it is no longer sufficient that the effects of relativity are considered in the form of perturbation energy corrections, and in order to obtain more accurutc numerical results, relativistic corrections should be made both for energy and for radial wavefunction.

Key words: autoionization, dielectronic recombination, dielectronic satellite spectra
