Abstract
A systematic study fa wide class of nonrelativistic models of b (b) ov er bar quarkonia is described. It is found that the potential V(r) = 0 .706380(root r-0.460442/r) + 8.81715 (all in GeV) with the b-quark mas s M(b) = 4.80303 GeV gives a satisfactory description of the experimen tal data below the threshold for strong decays (chi(2)/DF = 6.5/7). Li mitations and implications of this observation are discussed.
