An Contribution to the Hydrogen Lamb Shift from Virtual Light by Light Scattering
The radiative correction to the Lamb shift of order
induced by the light by light scattering insertion in external photons is
obtained. The new contribution turns out to be equal to
. Combining this contribution
with our previous results we obtain the complete correction of order
induced by all diagrams with closed electron loops.
This correction is kHz and kHz for the - and
-states in hydrogen, respectively.Comment: pages, Penn State Preprint PSU/TH/142, February 199
