Spectroscopic strengths of low-lying levels in $^{\mathrm{18}}$Ne

ORAL

Abstract

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