High-resolution in-beam particle-gamma coincidence spectroscopy

A short summary of the present status of prompt particle decays in the mass $A\sim 60$ region is presented. It includes recent results from a GAMMASPHERE experiment, which aimed at the combined high-resolution spectroscopy of light charged particles and $\gamma$-rays to allow for more detailed studies of known decays and the identification of new cases of discrete prompt proton and $\alpha$-particle emission from highly and superdeformed states
