Core-polarization corrected Dirac-Fock computations were performed, under assumption of so-called one-electron spectrum over-imposed on multi-electron spectrum, to predict levels and oscillator strengths for lowest transitions of so far mostly unknown highly ionized spectra of the rubidium isoelectronic series from Tc VII through Pb XLVI. To evaluate the accuracy of our predictions, calculations were also made for Mo VI spectrum, where experimental and other theoretical data are available. Behavior of oscillator strengths along the isoelectronic sequence was studied, exhibiting some relativistic features for highly ionized systems. The effect of collapse of the $4p^{6}4f_{5/2,7/2}$ levels along the sequence leads to change in the level ordering between Rh IX ($Z$ = 45) and Sn XIV ($Z$ = 50) spectra. We also carefully monitored the influence of core polarization (CP) on both energy levels and oscillator strengths. For energy levels, the CP contributions are small and quickly diminish along the isoelectronic sequence. For oscillator strengths the CP influence is much more profound not only near the neutral end of the sequence but also for highly ionized spectra. Moreover, the relative CP contribution to oscillator strengths of the $4f_{5/2,7/2}-5d_{3/2,5/2}$ transitions reaches extreme values in the vicinity of the collapse region, where the $4f_{5/2,7/2}$ levels fall below the $5d_{3/2,5/2}$ ones. Finally, the assumption of the so-called one-electron spectrum, i.e., arising from excitation of a single valence electron outside of the closed-shell core seems to be justified for all states in the spectra under consideration with exception of the $4f_{5/2,7/2}$ levels, which are heavily mixed with other states along the sequence.

在所谓的单电子光谱过度施加在多电子光谱上的假设下，进行了核极化校正的狄拉克-福克计算，以预测迄今为止大多数未知的铷高度电离光谱的最低跃迁的能级和振荡器强度从 Tc VII 到 Pb XLVI 的等电子系列。为了评估我们预测的准确性，还对 Mo VI 光谱进行了计算，其中可以获得实验和其他理论数据。研究了沿着等电子序列的振荡器强度的行为，展示了高度电离系统的一些相对论特征。倒塌的影响$4{磷}^{6}4F_{5/2,7/2}$ 沿序列的水平导致 Rh IX ($Z$ = 45) 和锡十四 ($Z$= 50) 光谱。我们还仔细监测了核心极化 (CP) 对能级和振荡器强度的影响。对于能级，CP 的贡献很小，并且沿着等电子序列迅速减少。对于振荡器强度，CP 的影响不仅在序列的中性端附近而且对于高度电离的光谱也更加深远。此外，相对 CP 对振荡器强度的贡献$4F_{5/2,7/2}-5d_{3/2,5/2}$ 过渡在坍塌区域附近达到极值，其中 $4F_{5/2,7/2}$ 水平低于 $5d_{3/2,5/2}$那些。最后，所谓的单电子谱的假设，即由封闭壳核外的单个价电子的激发引起的，似乎对于所考虑的谱中的所有状态都是合理的，除了$4F_{5/2,7/2}$ 级别，这些级别与序列中的其他状态严重混合。
