Abstract
A radiative correction to the Lamb shift of order α2(Zα)5m induced by the light by light scattering insertion in external photons is obtained. This new contribution turns out to be equal to -0.122(2)α2(Zα)5/(πn3)(mr/m)3m. Combining this contribution with our previous results we obtain the complete correction of order α2(Zα)5m induced by all diagrams with closed electron loops. This correction is 37.3(1) kHz and 4.67(1) kHz for the 1S- and 2S-states in hydrogen, respectively.
