Configurations and decay hindrances of high-K states in ¹⁸⁰Hf

NUCLEAR REACTIONS ¹⁸⁰Hf(²⁰⁷Pb, X), E=1.4 GeV; measured Eγ, Iγ, γγ-coin, delayed γ, level and isomer half-lives by γγ(t) and centroid-shift method using Gammasphere array and heavy-ion detector CHICO at ATLAS-ANL facility. ¹⁸⁰Hf; deduced high-spin levels, J, π, 2- and 4-qp states, multi-quasiparticle high-K states, rotational bands, reduced hindrances for E1, E2, E3, M1 and M2 transitions from isomers, (g_K-g_R)/Q₀ as function of Jπ, configurations. Comparison with theoretical calculations using Lipkin-Nogami approach for pairing, with blocking included. Systematics of high-K states in ¹⁸⁰Hf, ^180,182W, and ^182,184Os.
