Abstract
We use a variation of the Bethe-Salpeter equation to complete the calculation of the one-photon annihilation contribution to the hyperfine interval of positronium at order Our results are in accord with a quite different calculation independently done using an effective field theory approach. This completes the evaluation of all the terms. We give the total theoretical value for this interval and compare with experiment.
