Abstract
The reaction is important in stellar explosions, but its rate has been uncertain because of an expected state in that has never been conclusively observed. This state would provide a strong resonance and, depending on its excitation energy, could dominate the stellar reaction rate. We have observed this missing state by measuring the excitation function with a radioactive beam at the ORNL Holifield Radioactive Ion Beam Facility. We find that the state lies at a center-of-mass energy of ( ) and has a width of .
