Abstract
High-spin states of nuclei near doubly magic 56Ni were studied with
the reaction 28Si(36Ar,xpynz
) at 136 MeV beam energy.
The GAMMASPHERE array in conjunction with the 
charged-particle
detector array MICROBALL and neutron detectors were used to detect
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.
