Measurements were made on the gamma energies from Beg produced in the reaction Li/sup 7/(He/sup 3/,p)Be/sup 9/. For bombarding energies above 4.6 Mev there is a yield of 12 and 14.5-Mev gamma rays; since the threshold for forming Beg in a level at 14.39 Mev is at 4.56 Mev, the gamma rays were attributed to the decay of the 14.39-Mev state to the ground and first excited states. The gamma yield is not a monotonic function of bombarding energy, for the yield at 6.5 Mev is higher than at 5.5 or 7.5 Mev. Angular distributions of the gamma rays were measured from 30 to 140 deg and to within 25% the yield of 12 and 14.5 Mev gamma rays is isotropic. (P.C.H.)
