Abstract

A recently derived Fermi-Breit equation for a non-Coulombic vector interaction is used to construct a specific model for the charmonium spectrum. A scalar interaction term is also considered. Momentum-dependent terms, generated by the requirement of relativistic covariance, are included in the model.
