A new isotope with a 3.1-hr half life was produced in a 60-Mev proton bombardment of natural gadolinium. The isotope was identified to be Tb/sup 150/ by means of a mass separation performed on the chemically purified terbium fraction. Gamma-ray spectra have revealed an intense 640-kev peak belonging to Tb/sup 150/ decay. The gamma ray is probably the transition from the first- excited to the ground state in Gd/sup 150/. (auth)
