New states in 18Na and 19Mg observed in the two-proton decay of 19Mg

Previously unknown states in 18Na and 19Mg have been studied by measuring the trajectories of their decay products with microstrip detectors. Analyzing angular correlations of the fragments provided information on decay energies and widths of the parent states. The ground state of 18Na has been dete...
