摘要：

The decay of Ne-18 excited states into 2p+O-16 channel has been studied. The Ne-18 secondary beam, at 33 AMeV incident energy, was produced by fragmentation of a primary Ne-20 beam at the LNS-FRIBs facility. Coulomb excitation on a Pb-nat secondary target was found to be the main interaction process leading to the population of Ne-18 excited levels. The two-proton decay of the 6.15 MeV (1(-)) level has been detected, but in addition other high-lying states decaying via 2p emission were observed. A significant branching ratio of He-2 decay has been deduced from the analysis of the relative angle and energy correlation spectra of the two protons emitted from the 6.15 MeV (1(-)) state.
