Abstract

We have derived an equation for the β-ray angular distribution including Coulomb corrections, radiative corrections, induced effect, and higher-order nuclear matrices. With this equation and the experimental data on β-ray asymmetries in polarized B12 and N12, we conclude that the strength of the second-class induced tensor is fTfA=-(0.96±0.35)×10-3 in the limit of the impulse approximation. A possible modification of this value due to mesonic corrections is discussed.
