An interquark potential proposed recently to describe cc-bar and bb-bar systems is used to calculate some properties of the tt-bar system, for m/sub t/ = 40 and 45 GeV/c/sup 2/. It is shown how these properties (notably the 2S-1S spacing and the ratio GAMMA(2S..-->..e/sup +/e/sup -/)/GAMMA(1S..-->..e/sup +/e/sup -/ )) can be used to test the correctness of the underlying nonrelativsitic QQ-bar potential, allowing one to return to relativistic corrections in cc-bar and bb-bar bound states with improved confidence.
