Abstract
We calculate the energy spectrum and the one-photon and decays of charmonium and -quarkonium including their first-order relativistic corrections, within the context of the Buchmüller-Tye potential. Results seem to suggest that the confining potential is predominantly scalar since this assumption gives good agreement for spectra and for decay rates of and gives reasonable results for . For decays discrepancies persist unless the quarks have large anomalous moments, but the resolution of such discrepancies can probably be achieved by other means. As an interesting by-product of our investigations we find that for the nonrelativistically inhibited decay of the system, some rates are enhanced by a huge factor by first-order relativistic effects. When more data are available these decays should provide an additional testing ground for models of relativistic corrections.
