Low-spin structure of ⁸⁶₃₅Br₅₁ and ⁸⁶₃₆Kr₅₀ nuclei: The role of the g_7/2 neutron orbital

RADIOACTIVITY ⁸⁶Se, ⁸⁶Br(β^-)[from ²³⁵U(n, γ), E=thermal neutrons from PF1B-ILL-Grenoble facility using Lohengrin fission-fragment separator]; measured Eγ, Iγ, γγ-coin for both decays, γγ(θ) and γγ(linear polarization) for ⁸⁶Br decay using EXILL array of Ge detectors. ⁸⁶Br, ⁸⁶Kr; deduced levels, J, π, conversion coefficients, multipolarities, β feedings, logft. Comparison with large-scale shell-model calculations with refined interactions.

NUCLEAR REACTIONS ²³⁵U(n, γ), E=thermal neutrons from PF1B-ILL-Grenoble facility; measured Eγ, Iγ, γγ-coin using EXILL array of Ge detectors, level half-life by γγ(t). ⁸⁶Br; deduced levels, J, π, B(M2), B(E3).
