Abstract

A nonperturbative numerical evaluation of the one-photon electron self energy for the K- and L-shell states of hydrogen like ions with nuclear charge numbers Z = 1 to 5 is described. Our calculation for the 1S1/2 state has a numerical uncertainty of 0.8 Hz in atomic hydrogen, and for the L-shell states (2S1/2, 2P1/2 and 2P3/2) the numerical uncertainty is 1.0Hz. The method of evaluation for the ground state and for the excited states is described in detail. The numerical results are compared to results based on known terms in the expansion of the self energy in powers of Zα.
