利用高选择性的双中子击穿反应获得了()和()激发态的第一个光谱。用同位旋非守恒效应解释了这些原子核及其镜像对中同压模拟态之间的镜像能量差异。大规模壳层模型计算和数据之间的比较提供了迄今为止最令人信服的证据，即电磁和另一个同位旋非守恒相互作用的强制耦合，来源未知，需要获得良好的一致性。
The first spectroscopy of excited states in() and() has been obtained using the highly selective two-neutron knockout reaction. Mirror energy differences between isobaric analogue states in these nuclei and their mirror partners are interpreted in terms of isospin nonconserving effects. A comparison between large-scale shell-model calculations and data provides the most compelling evidence to date that both electromagnetic and an additional isospin nonconserving interactions forcouplings, of unknown origin, are required to obtain good agreement.
