    "abstract": "A description of low-energy scattering of pions and nuclei within a BUU\ntransport model is presented. Implementing different scenarios of medium\nmodifications, the mean free path of pions in nuclear matter at low momenta and\npion absorption reactions on nuclei have been studied and compared to data and\nto results obtained via quantum mechanical scattering theory. We show that even\nin a regime of a long pionic wave length the semi-classical transport model is\nstill a reliable framework for pion kinetic energies greater than ~20-30 MeV.\nResults are presented on pion-absorption cross sections in the regime of 10 MeV\n\u003c E(kin) \u003c 130 MeV and on photon-induced double-pion production at incident\nbeam energies of 400-500 MeV.",
