Shape coexistence in ⁷²Se investigated following the β decay of ⁷²Br

RADIOACTIVITY ⁷²Br(β⁺), (EC)[from ⁵⁸Ni(¹⁶O, pn), E=50 MeV]; measured Eγ, Iγ, γγ-coin, γγ(θ) using YRAST array. ⁷²Se; deduced levels, J, π, multipolarity, mixing ratio, β feedings, B(E2) strengths. Comparison with interacting boson model. Evidence of shape coexistence and configuration mixings.
