Abstract

Medium effects as a function of the mass number A are studied in the total photonuclear cross section from the Δ-resonance region up to the region where shadowing effects are known to exist. A consistent picture is obtained by simply assuming a density dependence of the different mechanisms of resonance broadening and shadowing. The Δ-mass shift is found to increase with A.
