Özet

The non-yrast states of the odd -odd nucleus Co-56 have been investigated by studying the y-rays induced in the predominantly fusion-evaporation reaction Fe-56(p,n gamma)Co-56 at an incident energy of 10 MeV. The y-rays were measured in-beam with four high-resolution MINIBALL-triple germanium (Ge) detectors. The experiment provided excellent data in gamma-gamma coincidences. The complex level scheme of Co-56 was constructed mainly based on the analysis of these gamma-gamma coincidences. The angular distributions of the gamma-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 the Co-56 nucleus, the analysis presented in this work has resulted in a large improvement in the knowledge of its structure.
