On the Possibility of Measuring the Ratio G A /G V by means of Polarized Ultracold Neutrons
The possibility of experimentally determining the ratio λ of the axial weak-interaction constant GA to the vector weak-interaction constant GV by simultaneously measuring the electron and neutrino asymmetries at the same setup is discussed. The proposed measurement and data-processing procedures are...

| description | The possibility of experimentally determining the ratio λ of the axial weak-interaction constant GA to the vector weak-interaction constant GV by simultaneously measuring the electron and neutrino asymmetries at the same setup is discussed. The proposed measurement and data-processing procedures are described in detail. 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. It is shown that this method makes it possible to measure λ to a precision at a level of 10−4. |
