Semi-empirical model potential calculations of oscillator strengths for Rydberg transitions in principal, sharp and diffuse series of gold one-electron spectrum are presented. Relativistic effects are fully included through solving Dirac equations and core–valence electron correlation is represented in core polarization picture by appropriate part in model potential. The dipole-moment operator of transition is modified in accordance. Systematic trends are investigated in oscillator strengths along the spectral series showing hydrogen-like behavior for large n effective quantum number of upper states of transitions. The so-called Cooper minimum in oscillator strengths is observed for principal series transitions. The influence of core–valence correlation (core polarization) on oscillator strengths along the spectral series is studied in detail​ demonstrating its importance even for transitions to rather highly excited Rydberg states with n18. In addition, excitation energies for some levels which positions in the neutral gold spectrum is unknown so far, are also predicted.

单电子金谱中里德伯格跃迁的半经验模型潜力研究

提出了在金一电子能谱的主要,尖锐和扩散序列中Rydberg跃迁的振荡器强度的半经验模型势计算。通过求解Dirac方程,可以完全包含相对论效应,并且在模型极化电势的适当部分,磁芯极化电子图片表示了核价电子相关性。跃迁的偶极矩算符根据进行了修改。研究了沿着频谱序列的振荡器强度的系统趋势,显示了大功率类氢行为ñ跃迁上态的有效量子数。对于主串联跃迁,观察到了所谓的库珀极小振荡器强度。详细研究了核-价相关性(核极化)对沿谱系列的振荡器强度的影响,表明了其重要性,即使对于跃迁到高激发的里德堡态也是如此。ñ18岁。此外,还预测了迄今为止尚不知道中性金谱中某些位置的某些能级的激发能。
