摘要：

We have completed the calculation of the one-photon-annihilation contribution to the positronium hyperfine interval at order m alpha(6). Our result for this contribution is -0.1256481(12)m alpha 6 = -2.344 MHz. The complete theoretical result for this interval is worked out, and comparison with experiment is discussed.
