N2 - Results of decay spectroscopy on nuclei in the vicinity of the doubly magic Ni48 are presented. The measurements were performed with a time projection chamber with optical readout which records tracks of ions and protons in the gaseous volume. Six decays of Ni48, including four events of two-proton ground-state radioactivity, were recorded. An advanced reconstruction procedure yielded the 2p decay energy for Ni48 of Q2p=1.29(4) MeV. In addition, the energy spectra of β-delayed protons emitted in the decays of Cr44 and Fe46, as well as half-lives and branching ratios, were determined. The results were found to be consistent with the previous measurements made with Si detectors. A new proton line in the decay of Cr44 corresponding to the decay energy of 760 keV is reported. The first evidence for the β2p decay of Fe46, based on one clear event, is shown.
