Study of $^{19}$Ne levels of Importance to $^{18}$F production in Novae
ORAL
Abstract
$^{18}$F is a relatively long-lived radioactive product of novae and its decay series is a direct probe of novae burning. The $^{18}$F(p,$\alpha)^{15}$O reaction dominates $^{18}$F destruction in novae but the rate is uncertain because the properties of important $^{19}$Ne levels have never been experimentally determined. There are several levels with uncertain spins and excitation energies that have only been estimated before. At ORNL, the $^{20}$Ne(p,d)$^{ 19}$Ne reaction was measured to study these important levels by using a 30 MeV beam of protons from the HRIBF tandem accelerator was used to bombard a carbon target implanted with $^{20}$Ne and outgoing particles were detected in a silicon strip detector array. Data will be shown and analysis discussed.
