More alpha /sup 6/1g alpha terms in positronium ground state splitting
The authors reconsider the calculation of the contribution to the positronium ground state splitting from the iteration of one-photon direct and exchange diagrams. New alpha /sup 6/1g alpha terms are found besides the previously known vacuum polarization contribution. The present situation in the co...

| Sumario: | The authors reconsider the calculation of the contribution to the positronium ground state splitting from the iteration of one-photon direct and exchange diagrams. New alpha /sup 6/1g alpha terms are found besides the previously known vacuum polarization contribution. The present situation in the comparison of theory and experiment is summarized. (9 refs). |
