We calculate the contributions of the axial current to top quark pair
production in e+ e- annihilation at threshold. The QCD dynamics is taken
into account by solving the Lippmann-Schwinger equation for the P wave
production using the QCD potential up to two loops. We demonstrate that the
dependence of the total and differential cross section on the polarization
of the e+ and e- beams allows for an independent extraction of the axial
current induced cross section.
