Description
One of the self-energy corrections of second order in α=e2/hc is calculated for 1s1/2, 2s1/2 and 2p1/2 states. The calculations involve the triple summation over the Dirac spectrum that was performed by the numerical method of the space discretization. This was achieved by the rearrangement of the summations in such a way that two of them were included in the corrections to the wave functions. ((orig.))
