Abstract :
Contributions to HFS and to the Lamb shift intervals of order α2(Zα)5 induced by a gauge invariant set of 19 topologically different graphs with two radiative photons inserted in the electron line are considered. Corrections both to HFS and Lamb shift induced by nine of these 19 diagrams have been calculated in the Fried-Yennie gauge
