Abstract
The lowest-order quantum electrodynamic corrections to the energy levels of quarks bound in a spherical cavity are evaluated over a wide range of values of the quark mass. It is found that the self-energy is positive for massless quarks and decreases smoothly as the quark mass increases. The interaction energy between quarks is also calculated and found to dominate the self-energy correction. For this model, the vacuum polarization correction vanishes.Keywords
