THE CALCULATION OF THE ENERGY LEVEL AND TRANSITION FOR THE Ni-LIKE IONS (Hf￣(44+)-Au￣(51+))

本文用多组态Ｄｉｒａｃ－Ｆｏｃｋ（ＭＣＤＦ）法计算了类镍Ｈｆ４４＋、Ｔａ４５＋、Ｗ４６＋、Ｒｅ４７＋、Ｐｔ５０＋、Ａｕ５１＋能级的精细结构和ｎ＝３—４偶极跃迁辐射的振子强度，得到了和实验符合得相当好的结果（对有实验数据的跃迁波长而言），并对组态的选取、核模型的影响、Ｂｒｅｉｔ修正和ＱＥＤ效应作了讨论指出对于本文研究体系，ＱＥＤ效应对跃迁的贡献可以忽略。

The fine structure and the oscillator strength (n= 3-4)of Ni-like ions (He44+ -An51+) are calculated by using MCDF method. The results agree with the observed values very well. The choice of configuration, nuclear model and the correction due to Breit and QED effect are discussed,it is pointed out that the contribution of QED may be neglected for the transition energy.
