Abstract

The helium-isotope mass-spectroscopy method for measuring the triton decay constant for various cases of the electron environment was used to determine the tritium half-life without allowance for decay to beta-electron bound states and to calculate the respective reduced half-life, which proved to be (fT 1/2) t = 1129.6 ± 30.0 s. The equations relating fT 1/2 to G A /G V made it possible to obtain the value of (G A /G V ) t = −1.2646 ± 0.0035 and to estimate the neutron lifetime at τ n = 890.3 ± 3.9(stat.) ± 1.4(syst.) s.
