Abstract
Prompt proton decay lines in 58Cu have been studied by means of high-resolution in-beam particle- $\gamma$ coincidence spectroscopy using the GAMMASPHERE Ge-detector array in conjunction with a dedicated set of ancillary detectors including four $\Delta E$- E silicon-strip telescopes. High-spin states in 58Cu have been populated via the heavy-ion fusion-evaporation reaction $\chem{^{28}Si({}^{36}Ar,1\alpha 1p 1n)}$ at 148 MeV beam energy. The full-width at half maximum for the proton peak could be reduced significantly compared to earlier experiments. The results indicate that only one prompt proton decay branch exists in the decay-out of the well-deformed band of 58Cu.
