Five prompt proton decay lines have been identified between deformed states in (59)Cu and three spherical states in (58)Ni by means of high-resolution in-beam particle-gamma gamma coincidence spectroscopy. The GAMMASPHERE array coupled to dedicated ancillary detectors including four Delta E-E silicon strip detectors was used to study high-spin states in (59)Cu. The multiple discrete proton lines are found to probe the wave functions of states in the decay-out regime of well- and superdeformed states.
