20. The (Formula presented) state of free muonium is metastable 15, decaying to (Formula presented) in about 1/7 sec. The value of (Formula presented) in that configuration leads to a factor of 4 reduction in the corresponding time dilation corrections of Eqs. (101112).

27. Our result in Eq. (17) is about an order of magnitude smaller than a similar calculation in Ref. 13.
28. Muonium annihilation was originally estimated in B. Pontecorvo, Zh. Eksp. Teor. Fiz. 33, 549 (1958) [Sov. Phys. JETP 6, 429 (1958)].
29. The singlet component of muonium does not decay into (Formula presented) due to helicity suppression. The triplet decay rate can be obtained by multiplying Eq. (17) by 4/3.

38. The expansion is analytic because the final decay state is far from any threshold. Bound state effects on the low energy (Formula presented) spectrum modify the total decay rate at (Formula presented) and can, therefore, be ignored in this analysis.
39. The right-hand side of the normalization condition would be the electromagnetic form factor of muonium at zero momentum transfer if the electron had no electric charge, and provided that the potential is instantaneous [which is true up to (Formula presented) corrections which we ignore]. Charge conservation or gauge invariance demands that this form factor equal unity.
