Abstract
High-spin states of nuclei near doubly magic 56Ni were studied with the reaction 28Si(36Ar,xpynz$\alpha$) at 136 MeV beam energy. The GAMMASPHERE array in conjunction with the $4\pi$ charged-particle detector array MICROBALL and neutron detectors were used to detect $\gamma$ rays in coincidence with evaporated light particles. The resulting extensive decay schemes of 54Fe, 54,55Co, 56,57Ni, and 58Cu are compared to shell model calculations in the fp shell.
