Total cross section measurement for the three double pion photoproduction channels on the proton
The total cross sections for the three γp → Nππ reactions have been measured for photon energies from 400 to 800 MeV. The γp → p π 0 π 0 and γp → n π + π 0 cross sections have never been measured before while the γp → p π + π − results are much improved compared to earlier data. These measurements w...
