High-spin level systematics in 177–182W: Yrast band anomaly in 180W

High-spin levels in 177–182W have been populated in (α,χnγ) reactions. Backbending-type behavior appears most prominently in 180W. The role of i132 neutrons and h92 protons in the 180W yrast behavior is examined. A strongly-coupled Kπ = 10+ band structure is identified in 182W, the first seniority-two i132 configuration to be characterized in a deformed nucleus.
