摘　　要：以氦原子能级的精细结构理论和任意强度磁场中氦原子的塞曼哈密顿为基础,对任意强度磁场中氦原子的所有里德堡态(组态为1snl,其中n和l可取一切可能值)的塞曼分裂效应进行了系统的研究,重点是在考虑线性塞曼效应的基础上进一步考虑了平方塞曼效应,借助不可约张量理论导出了氦原子各里德堡态的塞曼分裂能级的解析表达式,绘制了反映塞曼分裂特征的结构图。Based on the fine structure theory of helium and the Zeeman Hamiltonian of helium in magnetic field with arbitrary intensity,a systematic analysis of the Zeeman effect on all the Rydberg States of Helium（1 snl configuration,n and l equal to every possible value） is derived by virtue of irreducible tensor theory. The key points are the further consideration of the square Zeeman effects beyond the linear Zeeman effects,the deriving of the analytical expressions for the Zeeman splitting of Rydberg energy levels of helium,and the drawing of the structural diagrams that reflect the Zeeman splitting characteristics.
