Description
Much effort has been made to understand the origins of $^{18}$F in novae. Due to its relatively long half-life (~2 hours), $^{18}$F can survive until the nova envelope is transparent, and therefore can provide a sensitive diagnostic of nova nucleosynthesis. It is likely produced through the beta decay of $^{18}$Ne, which is itself produced (primarily) through the $^{17}$F(p,$\gamma$) reaction. Understanding the direct capture contribution to the $^{17}$F(p,$\gamma$) reaction is important to accurately model it. As such, the spectroscopic strengths of low-lying states in $^{18}$Ne are needed. At the University of Notre Dame a measurement of the $^{17}$F($d,n$) reaction has been performed using a beam produced by the TwinSol Low energy radioactive beam facility. The neutrons were detected using a combination of Versatile Array of Neutron Detectors (VANDLE) and UoM Deuterated Scintillator Array (UMDSA). Data will be shown and preliminary results discussed.
