Study of the $^{13}$C({\it d,n$_{0,1}$})$^{14}$N reaction below $E_{cm}$ = 400 keV
ORAL
Abstract
Several poorly understood reactions may contribute to heavy element inhomogeneous nucleosynthesis. Among these reactions, $^{13}$C({\it d,n}) has been studied in order to better understand the dynamics of this reaction and the proper way to extrapolate its S-factor. We have made detailed measurements of the angular distributions of the cross sections and the vector analyzing power for the {\it n$_{0}$} and the {\it n$_{1}$} reaction groups in the $E_{cm}$ range from 250 to 400 keV. The atomic beam polarized ion source and the TUNL mini-tandem supplied polarized deuterium beams which struck a thick, enriched $^{13}$C target. Nine organic liquid scintillator (BCI-501) neutron detectors were placed at forward and backwards angles. Angular coverage was from 0$^{\circ}$ to 158$^{\circ}$ with two detectors at $\pm$ 90$^{\circ}$ to control systematic effects. The data will be compared to the predictions of the direct reaction model.
