Abstract.
Excited states in neutron-rich 185Ta have been populated following the one-proton pickup reaction of 186W(18O,19F). In-beam γ -rays were measured in coincidence with scattered particles detected by a high-resolution ΔE -E Si telescope for reaction channel selection. Several low-lying levels including a T 1/2 = 0.9(3) μs isomer at 406 keV have been identified. A spin assignment of I = 3/2 and the 1/2+[411] Nilsson configuration are given to the isomer in comparison with the level energy systematics and the isomer decay rates in the region.
