As known, electron vacuum polarization by nuclear Coulomb field produces Uehling potential with the range . Similarly, neutrino vacuum polarization by boson field produces long range potential with a very large range . Measurements of macroscopic effects produced by potential give limits on the effective interaction constant which exceed Fermi constant by many orders of magnitude, while limits from spectroscopy of simple atomic systems are approaching the Standard Model predictions. In the present paper we consider limits on from hydrogen, muonium, positronium, deuteron, and molecular hydrogen. Constraints are also obtained on fifth force parameterised by Yukawa-type potential mediated by a scalar particle.
