Description

We present the details of our calculation of radiative corrections affecting the two-photon virtual-annihilation contributions to the positronium hyperfine splitting in order mα6(α4Ratsub infinityat). Our result, which is obtained in analytic form, is ΔE/sup A/atsub 2gammaat(α4Ratsub infinityat) < -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
