Neutral weak currents and relationship between the processes of nuclear scattering of electrons and neutrinos

The P-odd asymmetry of inelastic scattering of longitudinally polarized electrons by nonpolarized nuclei e-+A → e-+A' (where A, A' - some nuclei whose isospin differs by a unit) is found to be related to the difference in neutrino and antineu-- trino scattering cross sections of #betta#(anti #betta#)+A → #betta#(anti #betta#)-A' due to neutral currents. A' and A nuclear structure details are not significant for establishing this relation, they can be interpreted as elementary particles with a certain spin and isotopic spin. The isotopic structure of a neutral weak hadron current, predicted by the Salam-Weinberg model, as well as the absence of an isotensor component in electromagnetic current have been used
