The c¯c, b¯b, and t¯t spectra are investigated with the use of a semirelativistic potential model described in an earlier paper. Results for the energy levels, leptonic widths, and E1 transition widths are compared with the experimental data for c¯c, and b¯b, and predicted for t¯t. We also find that the quark-antiquark interaction can best be described by a quasistatic rather than a momentum-dependent potential, and propose a theoretical justification for this surprising conclusion.
