The {sup 20}Ne({ital p},{ital n}){sup 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 {similar_to}10{times} lower than an earlier experiment were obtained using the ``stripper loop`` storage ring to achieve {similar_to}2 {mu}s between beam bursts. We were able to see a weakly excited state at 2.65 MeV in {sup 20}Na with a {Delta}{ital l}=2 angular distribution. The angular distribution is consistent with a DWIA calculation assuming a 3{sup +} final state. The characteristics of this state are important to know for considerations of possible breakout in the hot CNO cycle in supernovae explosions.
