Towards the Limits of Existence of Nuclear Structure: Observation and First Spectroscopy of the Isotope 31K by Measuring Its Three-Proton Decay

The most remote isotope from the proton dripline (by 4 atomic mass units) has been observed: 31K. It is unbound with respect to three-proton (3 p ) emission, and its decays have been detected in flight by measuring the trajectories of all decay products using microstrip detectors. The 3 p emission p...
