Description

The two-proton radioactivity of the previously unknown 19Mg ground-state is observed by tracking the decay products in-flight. The trajectories of the 2p-decay products, 17Ne+p+p, have been measured by using tracking micro-strip detectors which allowed to reconstruct the 2pdecay vertices and fragment correlations. The half-life of 19Mg deduced from the measured vertex distribution is 4.0(15) ps in the system of 19Mg. The Q-value of the 2p-decay of the 19Mg groundstate inferred from the measured p–p–17Ne correlations is 0.75(5) MeV.
