New Measurements of spectroscopic factors for low-lying $^{16}$N levels

The origin of galactic $^{19}$F is uncertain, but thought to be created via the $^{15}$N(a,g)$^{19}$F reaction. However, many of the reaction rates involved are not well known. In particular, the $^{15}$N(n,g)$^{16}$N reaction bypasses $^{19}$F production at a rate that depends on neutron spectroscopic factors of low-lying $^{16}$N levels. The previously measured values ($\sim $0.5) differed greatly from the expected values of near unity, based on Oxbash calculations for the closed neutron shell of $^{15}$N. Knowledge of these spectroscopic factors is also important for fine-tuning shell model calculations. We have performed a new study of the $^{15}$N(d,p)$^{16}$N reaction in inverse kinematics with 100-MeV $^{15}$N beam from the HRIBF on a CD$_{2}$ target. Reaction protons were detected using the SIDAR and ORRUBA silicon detector arrays. The data and analysis will be presented. *Work supported in part by DOE and NSF.
