  The work concerns the quasielastic charged current neutrino-neutron and
antineutrino-proton interactions. Single, double, and triple spin asymmetries
are computed and analyzed. The spin asymmetries are sensitive to the axial form
factor of the nucleon. In particular, the target-recoil double spin asymmetry
and the lepton-target-recoil triple spin asymmetry depend strongly on the axial
form factor of the nucleon. Indeed, the sign and shape of these components
depend on the axial mass parameter. All the asymmetries, except the lepton
polarization, are observables well suited to study the nonstandard interactions
described by the second class current contribution.
