Improved Limit on Tensor Currents in the Weak Interaction from ⁸Li β Decay

RADIOACTIVITY ⁸Li(β^-); measured decay products, Eβ, Iβ; deduced tensor currents in the low-energy regime by examining the β-ν correlation of trapped ⁸Li ions with the Beta-decay Paul Trap. Comparison with the standard model prediction.
