    "abstract": "In the present paper we investigate a method to describe low-energy\nscattering events of pions and nuclei within a Boltzmann-Uehling-Uhlenbeck\n(BUU) transport model. Implementing different scenarios of medium\nmodifications, we studied the mean free path of pions in nuclear matter at low\nmomenta and compared pion absorption simulations to data. Pursuing these\nstudies we have shown, that also in a regime of a long pionic wave length the\nsemi-classical BUU model still generates reasonable results. We present results\non pi-induced events in the regime of 10 MeV \u003c Tkin \u003c 130 MeV and photo-induced\npi pi production at incident beam energies of 400-460 MeV.",
