The Lorentz Integral Transform method (LIT) is extended to pion photoproduction in the Δ-resonance region. The main focus lies on the solution of the conceptual difficulties which arise if energy-dependent operators for nucleon resonance excitations are considered. In order to demonstrate the applicability of our approach, we calculate the inclusive cross-section for π0-photoproduction off the deuteron within a simple pure resonance model.
