Improved Tensor Current Limit from ⁸B β Decay Including New Recoil-Order Calculations

RADIOACTIVITY ⁸B(β⁺) [from ⁶Li(³He, n)⁸B, E not given]; measured decay products, Eα, Iα, Eβ, Iβ, α-α-β-coin.; deduced β-ν angular correlation coefficient impacted by 2⁺ intruder state, Gamow-Teller decays. Comparison with new ab initio symmetry-adapted no-core shell-model calculations, available data. The Beta-decay Paul Trap, Argonne National Laboratory, the ATLAS facility.
