Description

Using a ''regularized potential'' we solve the Schroedinger equation including all spin dependent interactions nonperturbatively and calculate the radiative decays of heavy quarkonia. The influence of S-D mixing due to the tensor term is discussed. Applying the variational approach we investigate the influence of the relativistic kinetic energy on the bound state masses. (orig.)
