    "abstract": "We calculate the quasifree photoproduction of pions and eta mesons on nuclei\nfrom 12C to 208Pb. Assuming that for the quasifree process the cross sections\nfor pi/eta - photoproduction on a nucleon in medium are -- besides a lowering\ndue to Pauli blocking -- identical to those on a free nucleon, we use these as\nan input. The produced mesons or resonances then propagate through the nucleus\nwhere they can undergo several scattering and absorption processes. This final\nstate interaction, which leads to a lowering of the initial meson yield up to\n70%, we simulate in a coupled channel Boltzmann-Uehling-Uhlenbeck transport\nmodel. It allows us to study in detail the influence of Fermi motion, Pauli\nblocking and of the additional decay channels for nucleon resonances in medium\non the photoproduction cross section. The calculated total and differential\ncross sections are compared to experimental data and the influence of the\ndifferent medium effects on the cross sections is discussed in detail.",
