摘要：

A Bethe-Salpeter based bound-state formalism is applied to the calculation of recoil contributions of order m alpha(6) to hyperfine splitting in ground-state positronium. The calculation involves the numerical evaluation of two- and three-photon exchange diagrams along with derivative terms and many-potential contributions. After inclusion of all other contributions of the same order, a comparison with other calculations and experiment is made. [S1050-2947(98)02911-4].
