High-K states in 180Re

The 180Re nucleus has been studied at high angular momentum using the 174Yb(11B,5n) reaction at the Australian National University, with the CAESAR array for γ-ray detection and the Super-E solenoid for electron-conversion measurements. A τ = 13 ± 1 μs, 6-quasiparticle isomer and two intrinsic states and their associated bands have been established. The validity of the K quantum number is discussed
