We analyse the total photonuclear cross section in the energy range from 0.2 to 1.2 GeV, recently measured in Frascati on C, Be and U. By employing a simple resonance-hole model for the various baryonic resonances. which exist in the above range, we find that the experimental cross sections can be fairly well reproduced if one assumes that the nuclear medium strongly increases the width of all resonances above the DELTA.

Abstract
We analyse the total photonuclear cross section in the energy range from 0.2 to 1.2 GeV, recently measured in Frascati on C, Be and U. By employing a simple resonance-hole model for the various baryonic resonances. which exist in the above range, we find that the experimental cross sections can be fairly well reproduced if one assumes that the nuclear medium strongly increases the width of all resonances above the DELTA.
