Abstract:

Two-proton radioactivityfrom 18Ne is discussed in terms of sequential decay. The branch ratiosfor one-proton emission from excited states are calculated, which includingspectroscopic factors, obtained from a Shell-model calculation with realisticinteractions. The branch ratios show that the two-proton emission from the 1-state of 18Ne at 7.94 MeV is most likely to go through the sequential decay. The samemechanism is discussed for other excited states at higher energy by differentinteractions.
