It was found that the interference effects non-monotonically change with increasing atomic number Z in these two transitions. The strongest interference effect is near Z = 9 for 2s2p^3P0→2s^21S0 transition and near Z = 7 for the other.展开更多

The doubly excited states of Be-like Ar14+, He-like S14+ and Ar16+ ions are labeled by the quantum numbers K. T and A to show the systematic regularity. The results show that the spectroscopy of these states of Be-like ions is different from that of He-like ions because of the polarization and core penetration effects from the 1s2 core electrons展开更多
