Abstract
The reduced Bethe-Salpeter equation with scalar confinement and vector gluon exchange is applied to quark-antiquark bound states. The so-cal led intrinsic flaw of the Salpeter equation with static scalar confine ment is investigated. The notorious problem of narrow level spacings i s found to be remedied by taking into consideration the retardation ef fect of scalar confinement. A good fit for the mass spectrum of both h eavy and light quarkonium states is then obtained.
