Abstract: 
A description of the low-energy scattering of pions and nuclei within a BUU transport model is presented. Implementing different scenarios of medium modifications, the mean free path of pions in nuclear matter at low momenta and pion absorption reactions on nuclei have been studied and compared to data and to results obtained via quantum-mechanical scattering theory. We show that even in a regime of a long pionic wavelength the semi-classical transport model is still a reliable framework for pion kinetic energies greater than approximate to 20-30 MeV. Results are presented on pi-absorption cross-sections in the regime of 10 MeV <= T-kin(pi) <= 130 MeV and on photon-induced pi pi production at incident beam energies of 400-500 MeV.
