Abstract

For heavy quarkonia, a model with effective propagators (with a gluon covariant propagator) is applied. Bound state is described in the framework of Logunov-Tavkhelidze quasipotential approach. An one-gluon-exchange diagram is taken into account and the usual coupling constant is used. The s-states of heavy quarkonia are considered. The description of experimental data by quark models appears promising.
