Experiments on the Emission of Neutrinos fromP32

These experiments study energy and momentum conservation in beta-decay. The apparatus, improved over earlier experiments, permits increased accuracy in the measurement of the neutrino-electron angular correlation. It is concluded that the correlation is approximately ($1+cos\theta$). Determination of the nature of the dominant interaction in the beta-decay of ${\mathrm{P}}^{32}$ awaits measurement of the nuclear spin. If the spin is one, the tensor interaction is uniquely selected. If the spin is zero, the axial vector dominates. Spin 2 or higher is ruled out by the shape of the beta-spectrum.
