Abstract

The nuclear structure of ⁸⁹Zr was studied using the ⁸⁷Sr(α, 2nγ)⁸⁹Zr and ⁸⁶Sr(α, nγ)⁸⁹Zr reactions. Gamma-gamma coincidence and angular distributions of γ-rays were measured. New levels with spin values up to 23/2⁺ were proposed at 2454.0, 3109.3 and 3575.7 keV. The result of the present experiment is discussed on the basis of the shell model.
