“…We note that these results differ somewhat from those published previously in Ref. [18] where the simplified reconstruction procedure was used. The weighted average of the 2p decay energy is Q 2p = 1.29(4) MeV.…”

“…In such case, the signal from the emitted proton would be too weak to be registered. Previously, we have reported two events of this kind [17,18]. However, after re-analyzing the particle identification as described in section III A, the other event was found to be misidentified.…”

Results of decay spectroscopy on nuclei in vicinity of the doubly magic 48 Ni 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 48 Ni, including four events of twoproton ground-state radioactivity were recorded. An advanced reconstruction procedure yielded the 2p decay energy for 48 Ni of Q2p = 1.29(4) MeV. In addition, the energy spectra of β-delayed protons emitted in the decays of 44 Cr and 46 Fe, 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 44 Cr corresponding to the decay energy of 760 keV is reported. The first evidence for the β2p decay of 46 Fe, based on one clear event, is shown.
