TTP98-35 Relativistic Positronium Equation

The recoil corrections to the energy levels of leptonium are calculated to the order $\alpha^6$ and $\alpha^6 \log\alpha$ for all states except those having hyperfine mixing. A correction to the hyperfine operator is derived in which the potential appears in the denominator.
