  We investigate the pseudoscalar transition form factors of nucleon for
quasi-elastic scattering and \Delta resonance production in tau-neutrino
nucleon scattering via the charged current interactions. Although the
pseudoscalar form factors play an important role for the \tau production in
neutrino-nucleon scattering, these are not known well. In this article, we
examine their effects in quasi-elastic scattering and \Delta resonance
production and find that the cross section, Q^{2} distribution, and spin
polarization of the produced \tau^{\pm} leptons are quite sensitive to the
pseudoscalar form factors.
