TTP96-50 Eight-component differential equation for leptonium

It is shown that the potential for lepton-antilepton bound states (leptonium) is the Fourier transform of the first Born approximation to the QED scattering amplitude in an 8-component equation, while 16-component equations are excluded. The Fourier transform is exact at all {\sl cms} energies $ - \infty < E < \infty$; the resulting atomic spectrum is explicitly CPT-invariant.
