摘要：

We calculate the contribution of the six radiatively corrected light-by-light scattering graphs to the decay rate of orthopositronium. Our result is Γlight-by-light= -α2ln(1/α)ΓLO+9.0074(9)(α2/π2)ΓLO. Our result contains a known analytic logarithm plus a new constant term which contributes 0.000 350 μs-1 to the rate. © 1995 The American Physical Society.
