Zirconium in the form of Zirconium oxide (Zr02) and zirconium foil was bombarded with protons of various energies from the 100 Mev McGill synchrocyclotron. Niobium was separated from the irradiated material by ion exchange column chromatography. When quick separation of these isotopes was desired a method based on solvent extraction of Niobium was used. A short lived activity, not previously observed, was found in the chemically separated Niobium when zirconium was bombarded at about 40 Mev protons. Gamma rays belonging to this activity were studied on a 28 channel pulse height analyser. Two gamma rays of approximately 75 kev, 1100 kev as well as 511 kev positron annihilation radiation showed a half life of 10 minutes.
