Abstract
An upper limit for the mean life of the 3.56-Mev state in of 5× sec has been established by a Doppler shift method. This supports the , assignment for this level. It has also been established by a Doppler shift technique that the angular distribution of the recoil alphas arising from the reaction is symmetric about 90° in the center-of-mass system at the resonant bombarding energy of 2.56 Mev. At 2.93-Mev bombarding energy the angular distribution of the alphas is peaked forward of 90°.
