Abstract
Populating states in via the reaction in inverse kinematics with a beam, we have measured the proton-decay branching ratios of the levels at and and obtained an experimental upper limit on the branching ratio of the state. On the basis of the present and previous measurements, we assign spins and parities to the and states. We combine our branching ratios with independent measurements of the lifetimes of these states or their analogs to compute the resonance strengths and thereby the astrophysical rate of the reaction. We perform hydrodynamic calculations of nova outbursts with this new rate and analyze its impact on yields.
