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 θVh≲10-2 for the mass range 0.5-5 MeV of vh where a limit of only ≲10-1 previously existed.
