γ-ray spectroscopy of a four-quasiparticle isomer band in ¹⁷⁴Re

NUCLEAR REACTIONS ¹⁶⁰Dy(¹⁹F, 5n), E=107 MeV pulsed beam from the 14-UD Pelletron at the Australian National University]; measured prompt and delayed Eγ, Iγ, γγ-coin, half-lives of isomers by γ(t) and γγ(t) using the CAESAR HPGe detector array. ¹⁷⁴Re; deduced levels, J, π, bands, γ-branching ratios, four-quasiparticle Kπ=(14-) isomer, Nilsson configurations, g_K, Weisskopf hindrances and reduced hindrances for transitions from the (14-) isomer and the (8-) bandhead; calculated potential energy surfaces. Comparison with previous experimental results.
