The system p+ Ni has been investigated at laboratory energies from 0.75 to 5.00 MeV. Continuous yield curves in the (p, y) and (p,p y) channels were obtained with a resolution of about 2 keV. In the capture channel, 190 resonances were identified. For 56 resonances, in regions of possible analog states, y-ray spectra were measured. Spins of 28 of the stronger resonances were determined from y-ray angular distributions. Spins of the weaker resonances were inferred from their decay branching. Eighteen analog state candidates were identified, allowing a systematic survey of isobaric analogs up to 3 MeV in the parent Ni. Several of the analogs are fragmented, including the g9/g state at 3.550 MeV, for which a nearby companion at 3.480 MeV was found. A further 2 resonance 9 + some 0.7 MeV below the analog state at 2.839 MeV was also found. In addition to the resonant state information, the y decay spectra and angular distributions lead to the establishment of five new bound levels of Cu, at 2.993, 3.574, 3.729, 3.930, and 4.465 MeV. Nine levels, previously observed only in particle transfer reactions, at 3. 309, 3.551, 3.699, 4.072, 4.207, 4.307, 4,441, 4.530, and 4.917 MeV, were seen. The decay schemes of these and of many other levels were refined.
