Abstract
We study the spin properties of top quarks produced in collisions of p olarized photons in the threshold region. For a relatively heavy top q uark the influence of non-perturbative effects is small and its polari zation parameters can be predicted in perturbative QCD. The measuremen ts of the top polarization may allow a novel test of QCD in the ttBAR system. In particular, they may provide a new way to determine the pre cise value of alpha(s) and to study the properties of the top quark.
