Abstract
Excited states have been identified in the isotones W and Re, which were produced in fusion-evaporation reactions of a beam of 310-MeV Ni ions with an isotopically enriched Cd target. The strongest -ray transitions in W and Re are interpreted as continuing the regular sequence of states identified in lighter 85 isotones that are built upon 9/2 and 10 states, respectively. The half-life of Hf, the -decaying daughter of the decay of W, was measured with improved precision to be 840 30 ms.
