通过研究10 MeV入射能量下56 Fe（p，nγ）56 Co的熔合-蒸发反应中产生的γ射线，研究了奇-奇核56 Co的非衰变态。用四个高分辨率MINIBALL-三重锗（Ge）探测器测量γ射线束。该实验提供了极好的γ-γ符合数据。在对这些γ-γ符合进行分析的基础上，建立了56 Co的络合物能级方案。我们还分析了γ射线的角分布，使我们能够为这个核中的大多数激发态分配自旋宇称值。尽管以前做了大量的工作，研究56钴核，在这项工作中提出的分析，导致了一个很大的改进，其结构的知识。
The non-yrast states of the odd-odd nucleus56Co have been investigated by studying theγ-rays induced in the predominantly fusion-evaporation reaction56Fe(p,nγ)56Co at an incident energy of 10 MeV. Theγ-rays were measured in-beam with four high-resolution MINIBALL-triple germanium (Ge) detectors. The experiment provided excellent data inγ-γcoincidences. The complex level scheme of56Co was constructed mainly based on the analysis of theseγ-γcoincidences. The angular distributions of theγ-rays were also analysed and allowed us to assign spin-parity values to most of the excited states in this nucleus. Despite the extensive work previously done studying the56Co nucleus, the analysis presented in this work has resulted in a large improvement in the knowledge of its structure.
