$^{19}$Ne states studied with the new JENSA gas jet target
ORAL
Abstract
The observation of $^{18}$F decay in novae would provide a direct test of nova models. To interpret such observations, the nuclear reactions that create and destroy $^{18}$F in novae must be understood. The destruction primarily occurs through the $^{18}$F($p,\alpha$)$^{15}$O reaction via resonances from states in $^{19}$Ne. 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 $^{20}$Ne($p,d$)$^{19}$Ne 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.
