Discovery of low-lying E1 and M1 strengths in ²³²Th

NUCLEAR REACTIONS ²³²Th(γ, γ'), E=2-4 MeV; measured Eγ, Iγ, γγ(θ), integrated σ using HIγS facility; deduced widths. ²³²Th; deduced levels, J, π, multipolarity, B(M1), B(E1), branching ratios. Comparison of scissors mode summed B(M1) strengths with those in ²³²Th, ^235,236,238U, and with predictions of quasiparticle random-phase approximation (QRPA).
