Abstract
A quarkonium potential constructed by inverse-scattering methods from the masses and leptonic decay widths of the vector mesons provides a basis for extrapolation to heavier quark-antiquark bound states. Level spacings and leptonic widths are predicted for systems with ground-state masses up to 60 . It is found that present uncertainties in the potential at short distances would be most conclusively resolved by measurement of the leptonic decay rate. Less definitive but still of value would be determinations of the or level spacings, and measurement of the ratio of and leptonic widths. Other properties of the next quarkonium family are less sensitive indicators of short-range behavior, and can be anticipated with some confidence from experimental results already in hand. These serve to test further the flavor independence of the interquark potential.
