Abstract
The lifetime of the first excited state of (0.750 MeV, ) produced in the reaction was measured using the delayed-coincidence technique. A solid-state detector was used to measure the energies of the protons as well as to produce timing signals. The mean lifetime was determined to be (3.77±0.11)× sec. This result is in good agreement with an earlier value of (3.73±0.23)× sec obtained using a pulsed-beam method. Disagreement with weak-coupling collective-model predictions based on neighboring transitions is thus not removed.
