Description

The possibility of experimentally determining the ratio λ of the axial weak-interaction constant G$_A$ to the vector weak-interaction constant G$_V$ by simultaneously measuring the electron and neutrino asymmetries at the same setup is discussed. The proposed measurement and data-processing procedures are described. The determination of λ by the method in question permits disregarding the possible contribution of the Fierz interference term and dispensing with an accurate measurement of the neutron polarization.
