Magnetic dipole excitations of ⁵⁰Cr

NUCLEAR REACTIONS ⁵⁰Cr(γ, γ'), (polarized γ, γ'), E<9.7 MeV bremsstrahlung; measured Eγ, Iγ, γ(θ), γ-polarization asymmetry, integrated σ, γ-branching ratios. Experiments performed at Darmstadt S-DALINAC and TUNL High Intensity γ-ray Source (HIγS) facilities. ⁵⁰Cr; deduced levels, J, π, B(M1), reduced widths, configurations, M1 spin-flip transition. Discussed isovector rotation-like oscillations of 1+ states versus scissors-type mode. Comparison with Skyrme quasiparticle random-phase-approximation (QRPA) and the large-scale shell model (LSSM) calculations.
