Abstract. We investigate spectral properties of an effective Hamiltonian which is obtained as a scaling limit
of the Pauli-Fierz model in nonrelativistic quantum electrodynamics.
The Lamb shift of a hydrogen-like atom is derived as the lowest order approximation (in the fine structure
of an energy level shift of the effective Hamiltonian.
