塞曼效应的量子理论处理

在塞曼效应实验结果的基础上,从电子自旋的角度出发,用量子力学的观点对塞曼效应中能级及谱线的分裂情况进行解释;指出朗德g因子中用L(L+1)、S(S+1)、J(J+1)分别替代L2、S2、J2的正确性,并从朗德g因子的取值对正常塞曼效应和反常塞曼效应进行比较,对它们的区别与联系加以揭示。

Atomic structure and collision dynamics with highly charged ions

The research progresses on the investigations of atomic structure and collision dynamics with highly charged ions based on the heavy ion storage rings and electron ion beam traps in recent 20 years are reviewed.The structure part covers test of quantum electrodynamics and electron correlation in strong Coulomb field studied through dielectronic recombi-nation spectroscopy and VUV/x-ray spectroscopy.The collision dynamics part includes charge exchange dynamics in ion-atom collisions mainly in Bohr velocity region,ion-induced fragmentation mechanisms of molecules,hydrogen-bound and van de Waals bound clusters,interference,and phase information observed in ion-atom/molecule collisions.With this achievements,two aspects of theoretical studies related to low energy and relativistic energy collisions are presented.The applications of data relevant to key atomic processes like dielectronic recombination and charge exchanges involving highly charged ions are discussed.At the end of this review,some future prospects of research related to highly charged ions are proposed.

试谈原子体系中的相对论效应

本文论述了相对论效应在原子体系中是普遍存在的.相对论效应对元素性质特别是对重元素的性质有着显著的影响,例如,重元素中的一些“反常”的性质象镧系收缩、6S^2惰性电子对等与相对论效应有关,因此,在大学化学教学中应提及相对论效应.

Semi-Relativistic Two-Body States of Spinless Particles with a Scalar-Type Interaction Potential

A semi-relativistic quantum approximation for mutual scalar interaction potentials is outlined and discussed.Equations are consistent with two-body Dirac equations for bound states of zero total angular momentum. Two-body effects near the non-relativistic limit for a linear scalar potential is studied in some detail.
