Observation of two-proton radioactivity of (19)Mg by tracking the decay products
We have observed the two-proton radioactivity of the previously unknown 19Mg ground-state by tracking the decay products in-°ight. For the ¯rst time, the trajectories of the 2p-decay products, 17Ne+p+p, have been measured by using tracking micro-strip detectors which allowed to reconstruct the 2p-de...
