Abstract. A seven-quasiparticle isomer with $K^{\pi} = (49 /2^ + )$ and T 1/2 = 53 ( + 3 -7) ns has been identified in 179Ta. By comparing its excitation energy with results from multi-quasiparticle calculations that include the effects of blocking and residual nucleon-nucleon interactions, the isomer is assigned the $\pi^{3}$ (5/2 + [402], 7/2 + [404], $9/2^{-}[514]) \otimes \nu^{4}$ (5/2-[512], 7/2-[514], 7/2-[503], 9/2 + [624]) configuration. The decay of this isomer is found to be unusually fast, a feature that is attributed to a mixing with a specific collective level. The interaction strength is found to be orders of magnitude lower than that observed between interacting collective levels.

K-Mixing and fast decay of a seven-quasiparticle isomer in 179Ta
Abstract. A seven-quasiparticle isomer with $K^{\pi} = (49 /2^ + )$ and T 1/2 = 53 ( + 3 -7) ns has been identified in 179Ta. By comparing its excitation energy with results from multi-quasiparticle calculations that include the effects of blocking and residual nucleon-nucleon interactions, the isomer is assigned the $\pi^{3}$ (5/2 + [402], 7/2 + [404], $9/2^{-}[514]) \otimes \nu^{4}$ (5/2-[512], 7/2-[514], 7/2-[503], 9/2 + [624]) configuration. The decay of this isomer is found to be unusually fast, a feature that is attributed to a mixing with a specific collective level. The interaction strength is found to be orders of magnitude lower than that observed between interacting collective levels.
