Determination of the Beta-Decay Interaction from Electron-Neutrino Angular Correlation Experiments

Abstract

The methods used to obtain a series of measurements of the angular correlations in the allowed beta decay of described. Schematic diagrams of the apparatus used in various experiments are given. The results prove that the dominant interactions are vector for the Fermi type of decay and axial-vector for the Gamow-Teller decays with the dominant interaction form being VA. The present experiments do not exclude a possible tensor admixture of 10% or less. A scalar mixture of the same magnitude may also be present. (C.J.G.)
