Abstract

The elastic scattering of longitudinal and transversal neutrinos on a spinless nucleus have been discussed taking into account the charge, magnetic, anapole and electric dipole moments of fermions and their weak neutral currents. Compound structure of the neutrino interaction cross section with nuclei have been defined. Invariance of the considered process concerning the C - and P-operations have been investigated in the polarization type dependence.
