Pygmy dipole strength in ⁸⁶Kr and systematics of N=50 isotones

NUCLEAR REACTIONS ⁸⁶Kr(γ, γ'), (polarized γ, γ'), E<11.2 MeV; measured Eγ, Iγ, γγ(θ), widths, azimuthal asymmetry, integrated σ. ELBE accelerator facility at HZDR, and HIγS facility at TUNL. ⁸⁶Kr; deduced levels, PDR, J, π, branching ratios, photoabsorption σ(E), energy-weighted sums of photoabsorption σ. Comparison of photoabsorption σ with that from (γ, n) reaction.

NUCLEAR STRUCTURE ⁸⁶Kr, ⁸⁸Sr, ⁹⁰Zr, ⁹²Mo; calculated neutron skin thickness, B(E1), proton and neutron transition densities using QRPA calculations. Comparison with shell-model calculations.
