====== TTP94-28 Polarization in Top Quark Pair Production near Threshold ======
 
 
   <hidden TTP94-28  Polarization in Top Quark Pair Production near Threshold > The polarization dependent momentum distributions
 of top quarks and their decay products are calculated
 for $t\bar t$ production at future $e^+e^-$ colliders
 with polarized beams. The Green function formalism
 is applied to this reaction near energy threshold.
 The Lippmann--Schwinger equations for the $S$-wave and
 $P$-wave Green functions are solved numerically for the
 QCD chromostatic potential given by the two-loop formula
 at large momentum transfers and Richardson ansatz
 at intermediate and small ones.
 It is demonstrated that for the longitudinally polarized
 electron beam an optimally polarized sample of top quarks can
 be produced.
