A good understanding of the level structure of 19Ne around the proton threshold is critical to estimating the destruction of long-lived 18F in novae. Here we report the properties of levels in 19Ne in the excitation energy range of 6.9 ≤ Ex ≤ 8.4 MeV studied via the proton-transfer 18F(d,n)Ne* reaction at the Holifield Radioactive Ion Beam Facility. The populated 19Ne levels decay by breakup into p+18F and α+15O particles. The results presented in this manuscript are those of levels that are simultaneously observed from the breakup into both channels. An s-wave state is observed at 1468 keV above the proton threshold, which is a potential candidate for a predicted broad Jπ = 1/2+ state. The proton and α partial widths are deduced to be Γp = 228 ± 50 keV and Γα = 130 ± 30 keV for this state. © 2012 American Physical Society.
