Abstract
Several properties of the production and decay of from the nuclear reactions , have been studied The parameters measured were the isomeric yield ratio, the half-lives of the isomeric state and the ground state, the positron branching ratio of the ground state decay, and the cross section. The values obtained for these quantities are 0.689±0.069, 64.7±1.3 sec, 2.42±0.09 h, 2.73%±0.27%, and 1650±165 mb, respectively. In addition, an upper limit on the ratio of the cross section to the cross section was determined to be 1.5×. This leads to an upper limit on the cross section of approximately 2.5 mb. This work was performed using 14.7-MeV neutrons from the reaction.
