受双电荷负原子离子稳定性问题的启发，我们研究了原子核结合N电子所需的最小电荷。采用大和扩散的基组和多参考组态相互作用计算，确定为系统高达N = 19对应于元素周期表的最低三个周期的元素。对于这里考虑的元素X，我们的结果排除了稳定性，并给出了强有力的证据，没有其他稳定的原子二价阴离子存在。
Motivated by the stability problem for doubly charged negative atomic ions, we study the minimal charge required for an atomic nucleus to bind N electrons. Employing large and diffuse basis sets and multireference configuration interaction computations, is determined for systems up to N = 19 corresponding to elements from the lowest three periods of the periodic table. For those elements X considered here, our results rule out the stability of , and give strong evidence that no other stable atomic dianions exist.
