Spectroscopic strengths of low-lying levels in 18Ne

ORAL

Abstract

Much effort has been made to understand the origins of 18F in novae. Due to its relatively long half-life (~2 hours), 18F 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 18Ne, which is itself produced (primarily) through the 17F(p,γ) reaction. Understanding the direct capture contribution to the 17F(p,γ) reaction is important to accurately model it. As such, the spectroscopic strengths of low-lying states in 18Ne are needed. At the University of Notre Dame a measurement of the 17F(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 results will be discussed.
