The doubly magic nucleus [sup48]Ni has been observed for the first time at GANIL. The experiment was performed using a high intensity [sup58]Ni beam at 74.5 MeV/A on a nickel target. This T[subZ] = −4 nucleus is the most proton-rich nucleus ever observed, and is a good candidate for two-proton radioactivity. In this experiment, we also implanted around 280 [sup42]Cr, 50 [sup45]Fe and 100 [sup49]Ni isotopes, for which no experimental information about the decay is available
