Abstract

The Lamb Shift (LS) of Hydrogenlike atom is evaluated by a simple method of quantum electrodynamics in noncovariant form, based on the relativistic stationary Schrödinger equation. An induced term proportional to \overrightarrowp⁴ in the effective Hamiltonian is emphasized. Perturbative calculation of second order leads to the LS of 1S_1/2 state and that of 2S_1/2-2P_1/2 states in H atom with the high accuracy within 0.1%
