Abstract
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 J π = 1/2+ state. The proton and α partial widths are deduced to be p = 228 ± 50 keV and
α = 130 ± 30 keV for this state.
