    • -1 (inverse seconds). At Z = 1, this is equivalent to the "famous" value of 1.3 Hz which is nowadays most frequently quoted in the literature.

    • note
    • In a number of cases, the formulation of a quantum electrodynamic bound-state problem may be simplified drastically when employing the concepts of an effective low-energy field theory known as nonrelativistic quantum electrodynamics [19]. The basic idea consists in a correspondence between fully relativistic quantum electrodynamics and effective low-energy couplings between the electron and the radiation field, which may still lead to ultraviolet divergent expressions. However, the ultraviolet divergences may be matched against effective high-energy operators, which leads to a cancellation of the cutoff parameters. Within the context of higher-order binding corrections to the one-loop self-energy problem, this has been discussed in [23,24].

    • 2 in the propagator denominators of the second and third terms in curly brackets in Eq. (31) of [39] should be interchanged as indicated in Eq. (2). The further calculations described in [39], especially the double logarithms indicated in Eqs. (32) and (33) of [39], do not receive any corrections.

    • note
    • The other terms in Eq. (2) (not only the first three in curly brackets) may also generate imaginary parts, but they do so only if the reference state is a higher excited S or P state in which case one-photon decay is possible. Indeed, for higher excited S or P states, the additional imaginary energy shifts find a natural interpretation as radiative corrections to the one-photon decay width of these states [41].

    • The accuracy of the present calculation for the total radiative effects should therefore be estimated as roughly 20% for Z = 1 and Z = 2.
