Abstract: (APS)

Relativistic corrections to quarkonium energy levels and electric dipole transition rates are calculated. We find a consistent description with both electric confinement and tensor quark-antiquark forces at distances beyond that at which perturbative QCD should be valid. The preliminary masses of the χb and χb′ levels are described satisfactorily. The transitions ϒ′′→γχb, suppressed in some nonrelativistic models, are predicted to be observable here.
