Nuclear neutrino scattering and the structure of the weak neutral hadron current

Cross sections have been calculated for neutrino (antineutrino) scattering at nuclei $\bar{\nu}(\nu)A_i\to \nu(\bar{\nu})A_f$ due to neutral-current interact ion. A study is made of the neutrino excitation of isoscalar transitions in $^{12}С(0^+0\to 1^+0)$ and $^{14}N (1^+0\to 2^+0)$, which is sensitively dependent on the isoscalar component of the weak neutral hadron axial current. When the latter is present, the total neutral hadron axial current. When the latter is present, the total cross sections for neutrino and antineutrino excitation of the isoscalar transition in $^{14}N$ show considerable differences in relation to the energy $E_{\nu}$ of the neutrino (antineutrino).
