Abstract

Rotational states assigned to a Kπ = (5+) band in 18071Lu109 have been populated in the decay of a t1/2 ≥ 1 ms, two-quasiparticle isomer. Delayed γ-ray and x-ray coincidences were observed with the Gammasphere array following the deepinelastic reaction 23892U + 18072Hf. Gamma-ray coincidence and intensity data, comparisons with the level structure of the neighbouring odd-odd isotone, a g-factor analysis and theoretical predictions of multi-quasiparticle states, all support the assignment of the new band to the neutron-rich nucleus 180Lu.
