摘要：

Radioactive ion beams of F-17 were used to study several resonance states in Ne-18. Clear evidence for simultaneous two-proton emission from the 6.15 MeV state (J(pi) = l(-)) in Ne-18 has been observed with the reaction F-17 + H-1. Because of limited angular coverage, the data did not differentiate between the two possible mechanisms of simultaneous decay, diproton (He-2) emission or direct three-body decay. The two-proton partial width was found to be 21 +/- 3 eV assuming He-2 emission and 57 +/- 6 eV assuming three-body decay. The total width of the l(-) state was measured to be 50 +/- 5 keV. Several additional resonances that decay by single proton emission were also studied.
