摘　　要：利用相对论多组态Dirac-Fock(MCDF)理论和扩大活动空间方法,采取GraspVU程序包,对部分类Cu、类Zn、类Ga和类Ge金离子E1跃迁的跃迁波长、跃迁几率及振子强度等光谱参数进行了计算,所得到的波长数据与实验值符合的很好,并且精度要高于早期的MCDF方法.但是从这些有限的实验值和理论值可以看出,目前关于高Z元素的多电子体系的实验和理论数据较少,实验条件受限,同时也缺乏系统的理论研究.Based on multiconfiguration Dirac-Fock （MCDF） theory and active space approach, this paper uses the GraspVU, which is modified and extended from Grasp92 codes, to have the wavelength, transition probabilities and oscillator strength for n = 4 →n＇ = 4 transitions （El） in Cu-, Zn-, Ga- and Ge-like gold ions calculated. The computed wavelengths, compared with experimental measurements, are in better agreement than other MCDF calculations. As can be seen, a series of comprehensive researches of multi-electron system of high-Z elements need to be established from the limited existing experimental conditions and numbered experimental values.
