Abstract :
The total cross sections for the three γp → Nππ reactions have been measured for photon energies from 400 to 800 MeV. The γp → pπ0π0 and γp → nπ+π0 cross sections have never been measured before while the γp → pπ+π− results are much improved compared to earlier data. These measurements were performed with the large acceptance hadronic detector DAPHNE, at the tagged photon beam facility of the MAMI microtron in Mainz.
