Scattering and Bound States,rect application of QED to bound states has been discussed in the last chapter; it is complicated and needs improvements.

Hyperfine Shifts, Radiative Corrections,any level splittings are measured so precisely that their calculation would require second-order and even third-order perturbation theory. It is then much easier to take the fine structure from the Dirac equation, and to calculate the hyperfine structure as a perturbation of the Dirac equation.
