为了通过深度非弹性碰撞过程观察富含中子的稀土核，Abeam被加速到1000 MeV的能量，并单独轰击厚靶。伽马球被用来观测射线发射。由于所谓的不安全库仑激发，观察到许多新的态和跃迁。基态带已经扩展到，并且基于状态的旋转带，以前与十六极振动相关联，被观察到到。该带的准粒子结构已经确定，其不寻常的排列行为可能是由于静态中子对的可能猝灭。此外，基于[523]5/2准中子轨道的波段从延伸到，也表现出相同的不寻常的对准行为。
Abeam was accelerated to an energy of 1000 MeV and, separately, bombarded thick targets ofandin order to observe neutron-rich, rare-earth nuclei via deep-inelastic collision processes. Gammasphere was utilized to observe-ray emissions. Many new states and transitions were observed inas a result of so-called unsafe Coulomb excitation. The ground-state band inhas been extended toand a rotational band based on thestate, previously associated with a hexadecapole vibration, was observed up to. The quasiparticle configuration of theband has been determined, and its unusual alignment behavior may result from a possible quenching of static neutron pairing. In addition, the band based on the [523]5/2 quasineutron orbital inwas extended fromtoand also displays the same unusual alignment behavior.
