Abstract:

The mass levels of the charmonium and the bottonium are calculated based on the instantaneous ladder BS equation. The agreement with experiment is fairly good. We get smaller α_s than nonrelativistic analyses. Λ_\overlinems is estimated to be 80 - 130 MeV. The relativistic effects are not so small in the charmonium.
