Simultaneous impacts of nuclear shell structure and collectivity on β decay: Evidence from ⁸⁰Ga₄₉

RADIOACTIVITY ⁸⁰Ga(β^-), (IT) [from U(e^-, X)⁸⁰Ga, E=50 MeV]; measured decay products, Eβ, Iβ, Eγ, Iγ, γ-γ-coin.; deduced γ-ray energies and relative intensities, T_1/2, Gamow-Teller strength distribution, log ft, simultaneous impacts of nuclear shell structure and collectivity on B(GT) distribution and therefore the half-life of the precursor. Comparison with realistic shell-model calculation and systematic analysis. BEta Decay studies at Orsay (BEDO) setup, the Accelerator Linear and Tandem at Orsay (ALTO).
