  We have calculated the polarization of the final nucleon in charged current
quasi-elastic \nu -N scattering. We show that the longitudinal and transverse
polarizations, as well as their ratio exhibit simple dependence on the axial
form factor and their sensitivity to the axial mass is much stronger than that
of the cross section. This suggests that measurements of the polarization of
the nucleon in the high-statistics neutrino experiments could provide important
information on the axial form factor.
