Abstract
The photoproduction of two neutral pions from the deuteron has been studied for incident photon energies from 200 MeV to 820 MeV with the TAPS spectro meter at MAMI (Mainz Microtron). The total cross-section was determined and used to deduce the cross-section from the neutron. Due to the good statist ical quality of the data Dalitz plots for the three particles in the exit c hannel (pi (0)pi N-0) could be constructed. The invariant mass distribution s derived from them are presented in this paper. They indicate that the imp ortant reaction mechanism in the second resonance region is a sequential de cay pattern involving the population of the Delta (1232)-resonance as an in termediate state.
