摘要
根据扩展的相对论多组态Dirac Fock理论 ,采用“多功能相对论原子结构程序(GRASP2 )” ,计算了类铜金Au50 +的能级寿命和能级宽度及光谱跃迁波长、跃迁几率和振子强度 ,分析了轨道极化对能级的影响 ,指出了Au50 +离子内部的确存在轨道极化现象 .计算所得波长值与实验值符合较好 ,能级寿命与能级宽度的大小关系符合海森堡的能量与时间测不准原理 .
Based on the extended relativistic multiconfiguration Dirac Fock theory, the level lifetimes, level widths, wavelengths, probabilities and oscillator strengths of Au 50+ have been calculated using the general purpose relativistic atomic structure program. The wavelengths obtained are in good agreement with the experimental data available. It can be concluded that the orbit polarizing correction should be taken into account further.The relationship between the level lifetimes and the level widths satisfys the Heisenberg uncertainty principle.
