19 Ne states studied with the new JENSA gas jet target
Abstract
The observation of 18F decay in novae would provide a direct test of nova models. To interpret such observations, the nuclear reactions that create and destroy 18F in novae must be understood. The destruction primarily occurs through the 18F(p , α)15O reaction via resonances from states in 19Ne. Significant uncertainties remain concerning the properties of these states near the proton threshold at 6411 keV. We have used the newly-constructed JENSA (Jet Experiments in Nuclear Structure and Astrophysics) gas jet target at Oak Ridge National Laboratory to study these levels via the 20Ne(p , d)19Ne reaction. Deuterons were detected in the SIDAR Silicon Detector Array and the angular distributions were analyzed to determine the spins of astrophysically-relevant levels. The data and preliminary analysis will be presented.
