摘要：

We present the details of our calculation of radiative corrections affecting the two-photon virtual-annihilation contributions to the positronium hyperfine splitting in order m6(4R). Our result, which is obtained in analytic form, is 4R)=-13.13 MHz. We point out the gauge invariance of the result and demonstrate the cancellation of potential infrared contributions which appear at intermediate stages of the calculation. © 1979 The American Physical Society.
