Abstract

Excited states have been identified in the isotones 15974W and 16075Re, which were produced in fusion-evaporation reactions of a beam of 310-MeV 58Ni ions with an isotopically enriched 106Cd target. The strongest γ-ray transitions in 159W and 160Re are interpreted as continuing the regular sequence of states identified in lighter N= 85 isotones that are built upon 9/2− and 10+ states, respectively. The half-life of 155Hf, the β-decaying daughter of the α decay of 159W, was measured with improved precision to be 840 ± 30 ms.
