Abstract

The ${}^{20}{Ne}$ (p,n $)^{20}$ Na reaction at 135 MeV was studied experimentally using the beam-swinger neutron time-of-flight facility at the Indiana University Cyclotron Facility. Backgrounds ∼10× lower than an earlier experiment were obtained using the ‘‘stripper loop’’ storage ring to achieve ∼2 μs between beam bursts. We were able to see a weakly excited state at 2.65 MeV in ${}^{20}{Na}$ with a Δl=2 angular distribution. The angular distribution is consistent with a DWIA calculation assuming a $3^{+}$ final state. The characteristics of this state are important to know for considerations of possible breakout in the hot CNO cycle in supernovae explosions.
