Structures of the medium- to high-spin states in the doubly magic nucleus {sup 56}Ni have been investigated using the reaction {sup 28}Si({sup 36}Ar,thinsp2{alpha}) and the {gamma} -ray spectrometer Gammasphere in conjunction with the 4{pi} charged-particle detector array Microball. Two well-deformed rotational bands have been identified. There is evidence that one of the bands, which is identical to a sequence in the odd-odd neighbor {sup 58}Cu , partially decays via proton emission into the ground state of {sup 55}Co . Predictions of extensive large-scale shell-model and cranked Hartree-Fock and Hartree-Fock-Bogolyubov calculations are compared with the experimental data. {copyright} {ital 1999} {ital The American Physical Society}
