High-spin Shell-model States Near 56Ni

• High-spin states of nuclei near doubly magic Ni-56 were studied with the reaction Si-28(Ar-36, 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 Fe-54, Co-54,Co-55, Ni-56,Ni-57, and Cu-58 are compared to shell model calculations in the fp shell.
