High-resolution In-beam Particle Spectroscopy - New Results on Prompt Proton Emission from 58Cu

• Prompt proton decay lines in Cu-58 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 DeltaE-E silicon-strip telescopes. High-spin states in Cu-58 have been populated via the heavy-ion fusion-evaporation reaction Si-28(Ar-36, 1alpha1p1n) 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 Cu-58.
