    "abstract": "We analyse pion-nucleus reactions in a microscopic transport model of the BUU\ntype, which propagates nucleons, pions, deltas and N(1440)-resonances\nexplicitly in space and time. In particular we examine pion absorption and\ninelastic scattering cross sections for pion kinetic energies T(pi) =85-315MeV\nand various target masses. In general, the mass-dependence of the experimental\ndata is well described for energies up to the delta-resonance (\\approx 160 MeV)\nwhile the absorption cross sections are somewhat overestimated for the higher\nenergies. In addition we study the possible dynamical effects of delta- and\npion-potentials in the medium on various observables as well as alternative\nmodels for the in-medium delta-width.",
