Decay spectroscopy of ¹⁶⁰Eu: Quasiparticle configurations of excited states and structure of K^π = 4⁺ bandheads in ¹⁶⁰Gd

RADIOACTIVITY ^160,160mEu(β^-)[from U(p, X), E=480 MeV]; measured Eγ, Iγ, γγ-coin, γγ(θ) βγγ-coin; deduced logft, β-feeding intensities. ¹⁶⁰Eu; deduced J, π of the b-decaying isomeric states with preliminary J=1 and J=5 assignments, configurations. ¹⁶⁰Gd; deduced levels, J, π, transition intensities, δ, B(M1), B(E2), T_1/2 of the excited states populated in ¹⁶⁰Eu decay, band configurations. Comparison to previous experimental results. GRIFFIN spectrometer consisting of 15 HPGe clover detectors and surrounded by 7 LaBr₃(Ce) detectors for lifetime measurements at the TRIUMF-ISAC facility.
