Abstract. Two low-lying isomeric states in ¹⁶⁹Ta have been identified via ¹⁵⁹Tb(¹⁶O,6n<Gamma>)¹⁶⁹Ta reaction. Their half-lives are measured to be 28 ± 5 ns for the 9/2^- level and 17 ± 4 ns for the 5/2^- level by using the delayed <Gamma>-<Gamma> coincidence method. These two isomeric states are considered to be the bandheads with 9/2^-[514] and 1/2^-[541] configurations respectively.
