摘　　要：研究非典型耦合下二价原子精细结构能级的塞曼分裂问题,旨在将典型耦合(即ls耦合和jj耦合)下二价原子精细结构能级的塞曼分裂理论拓展到更为一般的情形。在具体计算中,以非典型耦合下的精细结构理论为基础,采用微扰论方法,导出了非典型耦合下计算二价原子精细结构能级塞曼分裂的一般理论公式,并应用该理论具体分析了组态的塞曼分裂结构。计算结果表明:非典型耦合下二价原子精细结构能级的塞曼分裂结构包含了从ls耦合渐变到jj耦合的各种情形,具有更好实用性;理论给出的塞曼分裂因子形式具有一般性,ls耦合和jj耦合下的因子都是其特例。In this paper, Zeeman effects of atoms with two valence electrons under nontypical coupling are studied, in order to extend the well-known theory of Zeeman effects of atoms with two valence electrons under typical couplings (namely LS coupling and jj coupling) to a general case. Based on the fine structure theory of atoms with two valence electrons under non-typical coupling and the method of perturbation, a general theory for the Zeeman effects of atoms with two valence electrons under nontypical coupling is provided and applied to configuration. The results show that Zeeman energy splitting structure of atoms with two valence electrons under non-typical coupling includes various cases between the LS coupling and jj coupling, and that the form of factor is general, with those under LS coupling and jj coupling being its special examples.
