Abstract ： Two low-lying isomeric states in 169 Ta have been identified via 159 Tb(l6 O, 6n γ )169 Ta reaction. Their half-lives are measured to be 28 ± 5ns for the 9/2- level and 17 ± 4 ns for the 5/2- level by using the delayed γ-γ coincidence method. These two isomeric states are considered to be the bandheads with 9/2- [514] and 1/2- [541] configurations, respectively. Possible neutron quasiparticle configuration for the ground state of 169 W is discussed.
