Abstract
In this paper the slope at of the Dirac form factor for the electron vertex in fourth order is calculated. The result is . This result affects the energy levels of hydrogenic atoms and can be represented as an addition to the interaction energy density of the electron with the external field in the form , where is the mass of the electron. This term contributes to the level shift in a hydrogenic atom an energy of . This calculation reduces the uncertainty in the theoretical result by about 50% to ± 0.1 MHz, which is about the size of the experimental error.
