Abstract: 
We have investigated pi(0)pi(0) and pi(+/-)pi(0) photoproduction off complex nuclei. Simulations have been performed by means of a semi-classical BUU transport model including a full coupled-channel treatment of the final state interactions. We show that the target mass dependence of the pi(0)pi(0) invariant mass spectrum as measured by the TAPS collaboration can be explained without introducing medium effects beyond absorption and quasielastic scattering of the final state particles. On the other hand, we find considerable discrepancies with the data in the pi(+/-)pi(0) channel, which are not understood.
