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 \gamma -ray detection and the Super-E solenoid for electron-conversion measurements. A \tau =13\pm 1 \mu s, 6-quasiparticle isomer and two intrinsic states and their associated bands have been established. The validity of the K quantum number is discussed.
