Abstract: The β-asymmetry parameter A for the pure Gamow-Teller decay of 114In is reported. The low-temperature
nuclear orientation method was combined with a GEANT4-based simulation code allowing us, for the first time, to
address in detail the effects of scattering and the magnetic field. The result, A = −0.994 ± 0.010stat ± 0.010syst,
constitutes the most accurate value for the asymmetry parameter of a nuclear β transition to date. The value is in
agreement with the Standard Model prediction of A = −1 and provides new limits on tensor-type charged weak
