Medium-spin states of the neutron-rich nucleus ⁸⁷Br

NUCLEAR REACTIONS ²³⁵U(n, F), E=cold neutrons; measured Eγ, Iγ, γγ-coin, (γ rays from complementary fission fragments of ^146,147La)γγ-coin, γγ(θ) using EXILL array of Ge detectors at the PF1B facility of ILL-Grenoble. ⁸⁷Br; deduced high-spin levels, J, π, bands, γ-ray branching ratios, multipolarities, mixing ratios, configurations; calculated levels, J, π, bands, proton and neutron occupations of excited states using shell-model. Comparison of 9/2+ band in ⁸⁷Br with g.s. bands of ⁸⁶Se and ⁸⁸Kr.
