摘要 在相对论多组态Dirac-Fock(MCDF)理论方法基础上,通过系统考虑量子电动力学(QED)效应、Breit相互作用和弛豫效应,详细研究了类锌金离子Au49+的能级结构以及涉及M壳层激发态各种可能的辐射和Auger衰变过程.总结了QED效应和Breit相互作用对类锌金离子Au49+的M壳层激发态能级影响的一般规律.指出了随M壳层洞态的变化,主要的辐射衰变和Auger衰变的退激发特性.计算得到的部分辐射衰变能与已有的实验观测和理论计算结果作了比较,符合的很好. The level structures and various decay properties of the M-shell excited states of Zn-like Au^49+ ions are studied by using relativistic multi-configuration Dirac-Fock (MCDF)method, with the correction of relativity effect, quantum-electrodynamical (QED) effect, Breit interaction and relaxation effect. The calculated radiation transition energies are in good agreement with the existing experimental data and better than the previous calculations. Based on those studies, the decay characteristic of the M-shell single excited states are further discussed systematically.
