在RIKEN Nishina中心的RIBF装置的飞行裂变实验中研究了低能激发态。最先进的BigRIPS和EURICA装置的结合，使得对年至年的衰变进行了非常精确的研究，并提供了关于衰变序列和延迟中子发射分支的第一个实验信息。因此，我们报告了近60个以前未发现的跃迁，其中21个新的能级。证据的位置，因此寻求后，和资历国家提供。此外，在奇-奇富中子钴同位素中存在低自旋衰变异构体的质量得到证实。新的实验信息相比，简单的壳模型计算，包括只有中子激发theshells。结果表明，在一般情况下，计算重现所观察到的状态。
Low-lying excited states inhave been investigated in an in-flight fission experiment at the RIBF facility of the RIKEN Nishina Center. The combination of the state-of-the-art BigRIPS and EURICA setups has allowed for a very accurate study of thedecay fromto, and has provided first experimental information on the decay sequenceand on the delayed neutron-emission branch. Accordingly, we report nearly 60 previously unobservedtransitions which deexcite 21 new levels in. Evidence for the location of the so-sought-after, andseniority states is provided. As well, the existence of a low-spin-decaying isomer in odd-odd neutron-rich Co isotopes is confirmed for mass. The new experimental information is compared to simple shell-model calculations including only neutron excitations across theshells. It is shown that, in general, the calculations reproduce well the observed states.
