Measurements of Asymmetries in the Decay of Polarized Neutrons

Abstract

Previous measurements on the decay of polarized neutrons showed it to be non-isotropic with respect to the neutron spin. The coefficient for the correlation between the direction of emission of the beta particles and the neutron spin was shown to be too large in absolute value because of an interference from the correlation of neutrino direction with neutron spin. This correlation, of fundamental interest in beta-decay theory, was measured. The experimental apparatus is shown, and the results are tabulated. (D.E.B.)
