Abstract
The differential cross section of the g + g →t + t →(b + l + νl) + (b + l + νl) process near threshold is derived. A significant angular correlation of the charged leptons is predicted. Observation of the angular correlation will indicate that the spin of the gluon is one and that depolarization of the top-quark due to hadronization is negligible.Keywords
