Abstract

We have set limits on contributions of scalar interactions to nuclear β decay. A magneto-optical trap provides a localized source of atoms suspended in space, so the low-energy recoiling nuclei can freely escape and be detected in coincidence with the β. This allows reconstruction of the neutrino momentum, and the measurement of the β-ν correlation, in a more direct fashion than previously possible. The β-ν correlation parameter of the 0⁺ → 0⁺ pure Fermi decay of ³⁸K^m is ã= 0.9981 ± 0.0030 _-0.0037^+0.0032, consistent with the standard model prediction ã = 1.
