    "abstract": "We calculate the total photoabsorption cross section on nuclei in the energy\nrange from 300 MeV to 1 GeV within the framework of a semi-classical phase\nspace model. Besides medium modifications like Fermi motion and Pauli blocking\nwe focus on the collision broadening of the involved resonances. The resonance\ncontributions to the elementary cross section are fixed by fits to partial wave\namplitudes of pion photoproduction. The cross sections for $N \\, R \\to N \\, N$,\nneeded for the calculation of collision broadening, are obtained by detailed\nbalance from a fit to $N \\, N \\to N \\, N \\, \\pi$ cross sections. We show that a\nreasonable collision broadening is not able to explain the experimentally\nobserved disappearance of the $D_{13}(1520)$-resonance in the photoabsorption\ncross section on nuclei.",
