It is proposed to study the dynamical processes in atomic transitions dominated by strong multi-electron interactions. The intent is to develop physically realistic and computationally manageable theoretical procedures which can be applied to studies of more complex atomic transitions. Emphasis will be given to processes dominated by doubly excited states, both below and above the ionization threshold of quasi-two-electron atoms (two actively interacting electrons outside an easily pularizable cone). Applications will be made to single and multi-step transitions in alkaline earth and other quasi-two-electron atoms.

提出了以强多电子相互作用为主的原子跃迁动力学过程的研究。其目的是发展物理上现实的和计算上可管理的理论程序，可应用于研究更复杂的原子跃迁。重点将放在由双激发态主导的过程中，这些过程既低于也高于准双电子原子的电离阈值（两个活跃的相互作用的电子在一个容易扩散的锥体外）。将应用于碱土和其他准双电子原子的单步和多步跃迁。
