Abstract

Binding energy of the 11^- state (ortho-positronium) in QED is calculated using the one-photon exchange Bethe-Salpeter equation in the Feynman and Coulomb gauges for different coupling constants α\alpha. Calculations show there is a remarkable difference in values of the binding energy for different coupling constants in these two gauges.
