Abstract
The single photon annihilation contributions for the positronium groun d state hyperfine splitting are calculated analytically to order m(e) alpha(6) using nonrelativistic QED. Based on intuitive physical argume nts the same result can also be determined using results from previous calculations. Our result completes the hyperfine splitting calculatio n to order m(e) alpha(6). We compare the theoretical prediction with t he most recent experimental measurement.
