The effects of four-Fermi-type new interactions are studied in top-qua
rk pair production and their subsequent decays at future e(+)e(-) coll
iders. Secondary-lepton-energy distributions are calculated for arbitr
ary longitudinal beam polarizations. An optimal-observables procedure
is applied for the determination of new parameters. [S0556-2821(98)036
