Abstract
The quantum electrodynamical effects of helium fine-structure splitting hav e been studied. The Douglass and Kroll result at order m alpha(6) is obtain ed in a simple way using the time-ordered perturbation technique. The logar ithmic correction at order m alpha(7) ln alpha, as calculated by Tao Zhang is rederived and verified.
