中文摘要：

根据扩展的相对论多组态Dirac-Fock理论,采用“全相对论原子结构程序（GRASP2）”,考虑重要核的有限体积效应、量子电动力学效应（QED）和Breit修正以及组态间的相互作用,计算类镓Au^48＋的能级寿命、能级宽度、跃迁波长、跃迁几率和振子强度。结果表明：计算所得的波长与最新的实验数据及其他参考数据较吻合;能级寿命与能级宽度的关系符合海森保的能量与时间测不准原理;在类镓Au^48＋的跃迁中,3d-4f是一条较强的通道。

英文摘要：

Based on the extended relativistic multi-configuration Dirac-Fock theory, with quantum electro dynamical （QED） effect and Breit correction, the level lifetime, level widths, the transition wavelengths, transition probabilities and oscillator strengths of Au^48＋ were calculated with the general-purpose relativistic atomic structure program （GRASp^2）. The important nuclear volume and configuration interaction were considered in the program. The results show that the obtained wavelengths are in good agreement with the recently experimental data and other theoretical values. The relationship between the level lifetime and the level widths satisfies the Heisenberg uncertainty principle. The transition of 3d-4f is the stronger transition channel of Ga-like Au^48＋ transitions.
