NONRELATIVISTIC MODEL FOR $b\OVERLINE{b}$ QUARKONIA

Abstract

Experimental data for $b\bar{b}$ quarkonia have been compared with the predictions of a variety of nonrelativistic quark models. It is found that a potential $a\sqrt{r} - b/r +$ const gives good agreement, while many others do not. Some implications of this observation are discussed.
