Abstract

The consistency of the vector coupling constant extracted from the superallowed 0⁺→0⁺ nuclear β-decays with different maximal energies allows one to obtain a new limit on the mixing of the electron and heavy neutrinos: sin² θ_Vh≲10^-2 for the mass range 0.5-5 MeV of v_h where a limit of only ≲10^-1 previously existed.
